announces, “Fuel cell: a cell producing an electric current directly from a chemical reaction.” Fuel cells were thought of in 1839 by Sir William Grove who was known as “Father of the Fuel Cell.” In the article “History of Fuel Cells” the author states, “ Sir William Grove discovered that it may be possible to generate electricity by reversing the electrolysis of water.” But it wasn’t until 1889 when two researchers looked further into Sir William Grove’s studies. In the article “History of Fuel Cells”
developed are the hydrogen fuel cell and electric battery vehicles. Both of which provide pros and cons within the system, on the environment and cost wise. Hydrogen fuel cell vehicles A hydrogen fuel cell is an electrochemical cell which directly converts the chemical energy in hydrogen and oxygen to electricity with pure water (figure 1). In general fuel cells have a similar arrangement which consists of an electrolyte and two electrodes, but there are many types of fuel cells which are classified

The Future of Hydrogen Fuel Cells The present global economy is nearly entirely dependent on petroleum and crude oil imports from the Middle East. Where the current situation stands now, oil prices will continue to skyrocket and the environmental impact will continue becoming greater if no form of alternative energy is implemented to a greater extent within the coming years. However, to this effect, the industrial cost of producing such forms of alternative energy is in itself primarily composed
Hydrogen Fuel cell technology Hydrogen fuel cell is a device which converts chemical energy into electrical energy. The cell uses hydrogen and oxygen as the chemicals (Rose, 2013). This cell is like a battery and releases energy in one way from going negative to positive (government of Canada, 2013). The fuel cell is separated by an electrolyte, which causes the electrons to travel around in a circuit creating energy (government of Canada, 2013).The hydrogen travels across this electrolyte combining
Hydrogen fuel cells are a source of alternative energy. With no negative effects on the environment, they could become extremely popular. A hydrogen fuel cell combines hydrogen and oxygen to create water and energy. These simple energy source’s only drawback is how explosive the hydrogen gas inside is. Discussing with corporate manager, Andrew Dicks, we look into possible solutions and benefits for hydrogen fuel cells. Hydrogen fuel cells are an alternative source of energy. Unlike fossil fuels, hydrogen
recharging due to the limited storage capacities of batteries, it was faster to fuel a gas car than recharge an electric car, and finally, the mass production of the gas car lowered its price significantly compared to the electric car. Present day, the conventional gas powered vehicle is still preferred over electric cars, but advances in hydrogen fuel cell technology are making the option of owning a hydrogen fuel cell powered car more of a possibility as well as highlighting the benefits of other
Fuel Cell Technology Fuel Cells are a hot topic these days between the soon to come fuel cell cars that Toyota and Honda plan on unveiling this year and the $1.2 billion president Bush announced he would dedicate to fuel cell research during his State of the Union address. The least efficient of these electrochemical energy converters are at least as efficient as internal combustion engines and many are doubly as efficient when using special techniques. Exhaust from fuel cells is extremely
A fuel cell is mainly used to provide electricity from chemical reactions. It harnesses the chemical energy of hydrogen and oxygen to generate electricity without combustion one of the basic types of fuel cells is the Polymer Electrolyte Membrane Fuel Cell (PEMFC). This section will give a general description of its parts, how do they function and the material they are consisted of. 3.2 Background Polymer electrolyte membrane fuel cells operate at relatively low temperatures, around 80°C (176°F)
Hydrogen Fuel Cells Vs. Gasoline: Who’s Down With HFC? ABSTRACT: The world’s oil supply is a diminishing nonrenewable resource. Soon, a new fuel for automobiles will be needed. Hydrogen fuel cells may very well become the chief replacement for gasoline in our society. INTRODUCTION: In our busy world today, we often find ourselves surrounded by vehicles. But how often do we ponder about by which means these vehicles are running? Vehicles are fueled by gasoline, a gradually diminishing resource
Introduction: A fuel cell is a device that converts the chemical energy from a fuel into electricity through a chemical reaction of positively charged hydrogen ions with oxygen or another oxidizing agent. Fuel cells are different from batteries in that they require a continuous source of fuel and oxygen or air to sustain the chemical reaction, whereas in a battery the chemicals present in the battery react with each other to generate an electromotive (emf). Fuel cells can produce electricity
A H2/O2 proton−exchange membrane fuel cell (PEMFC) is a clean, sustainable energy source and suitable for the operation of small electronic device [1]. Among many problems that still exist for PEMFC, the sluggish reactions at the cathode electrode and poor mass transport of protons and electron decrease the fuel cell performance by increasing the activation overvoltage, or activation loss [2]. This problem can, however, be solved by raising the fuel-cell operating temperature [3], but only up to
and the recent use of hydraulic fracturing which has caused environmental and social dispute, I chose to undertake the extended project qualification related to this, energy, as chemistry leads these efforts. In my EPQ, I discuss whether hydrogen fuel cells are the future to generating electricity. The project has improved my primary and secondary research skills, beneficial for independent reports, and enhanced my chemistry vocabulary- new definitions such as Fenton’s reagents and super acids. Furthermore
Hydrogen: Car Power of the Future Abstract Recent years have shown an increasingly large need for a practical renewable energy source for such reasons as diminishing fossil fuels and increases in greenhouse gasses. Hydrogen appears to be a way out of this gasoline-dug hole, or at least, a way out in the future. Hydrogen fuel cell cars are being engineered as we speak as the technologies to refuel them cleanly are being proposed. Unfortunately, most of the technologies associated with hydrogen are still
8% more than that of helium. Hydrogen was used in airships and zeppelins for more than 20 years during the beginning of the 20th century. This practice stopped abruptly after the German airship Hindenburg disaster over New Jersey. It is used in fuel cells to create electricity, and to power cars and planes. Liquid hydrogen is mixed with liquid oxygen to form a cryogenic liquid that is burnt in Solid Rocket Boosters to power the space shuttle. Hydrogen is used to fill weather balloons because of its
applying an electric current to water, the resulting reaction produced both oxygen and hydrogen gases. This discovery eventually gave birth to the concept of the fuel cell. In essence, a fuel cell is no more complex than performing electrolysis in reverse. In 1839, a Swiss chemist, by the name of Christian Schoenbein, performed the first fuel cell experiment wherein he combined oxygen and hydrogen to produce water and a small electric current. Only six short years later, in 1845, Sir William Grove utilized
deal with. There sure is a lot of misinformation about hydrogen gone to public, so here are the basic facts about hydrogen as a power source according to the Nuts & Volts Magazine. Hydrogen on earth is not a fuel. It is only an energy carrier. Following the definition of the word fuel, fuel is a substance that is capable of delivering new energy when burning or other chemical reaction occurs. On the other hand energy carrier is a substance that is only able to move previously acquired energy from
produce no carbon when they are operating. Another great thing about electric vehicles is that they can be powered by electricity produced from multiple energy sources. The electricity can come from nuclear, hydro, solar, wind, biofuel, and even fossil fuel sources. Most of these sources are almost entirely produced and provided for here in the U.S. by local natural resources. Electric vehicles would greatly help the U.S. economy and also diminish our reliance on imported oil. The U.S. also already
Fuel of the Future It is obvious that this country has a knack for vast and rapid consumption of oil. Increases in greenhouse gas emissions, global warming threats and surging gas prices are just some of the warning signs. In the last two decades, this country has made great bounds in new, energy efficient technologies that have played a major role in the United States’ energy conservation efforts. “It’s not about turning off the lights or unplugging the refrigerator. It is a story about
late 20th century to now that new fuels have surfaced to challenge the might of gasoline. One type of alternative energy that can be used instead of gasoline is hydrogen fuel cells. Ever since 2003 when President Bush announced the Hydrogen Fuel Initiative car companies have been trying to develop Hydrogen fuel cell cars that are cost effective and practical. Alone the USA has invested billions of dollars on fuel cell research and development. Hydrogen fuel cells are practical because it can generate
