Technology has evolved in various ways over time. As many of us know medicine is a huge part of our lives that chemistry has advanced, along with various other things we need. Another thing chemistry has improved is batteries or fuel cells, like what is in a TV remote or a car. Also chemistry has helped improve gasoline for automobiles and other necessities for everyday use. This includes gasoline, jet fuel, kerosene, and diesel. A hydrogen fuel cell is what converts chemical stored energy by hydrogen fuel into electricity. Hydrogen fuel is very similar to normal batteries like what we would find in a car or a clock, but differences are present between the two. Like a battery, the fuel cells using hydrogen and oxygen are used to power devices that use electricity. While both batteries and fuel cells convert chemical energy to electrical energy, batteries store the chemical energy inside the battery. This may be efficient if you plan to recharge a battery, but the creators of fuel cells had other plans of more efficient ways to supply electricity; of course using fuel cells. The big difference between fuel cells and batteries is they do not need recharging. Rather than storing energy inside itself, a hydrogen fuel cell uses a supply of chemical energy from outside! This is stored in the hydrogen that is supplied to the anode. The fuel cells consume hydrogen and oxygen, and when continually supplied, (waste product being water, which of course, is removed) electricity is successfully generated! Before the discovery of the hydrogen fuel cells, or before they were put into use, everyone was forced to store energy in a regular battery and keep recharging to get electricity. Hydrogen fuel cells are not extremely popular now because t... ... middle of paper ... ...Biodiesel is usually made from plant oils and animal fats with lots of chemical reactions. It is non-toxic and renewable making this a huge asset. Biodiesel comes from plants and animals so it is easy to renew it from farming and recycling. Biodiesel can be used straight through a regular diesel engine. It is most efficient if it is blended with diesel at certain percentage. It is expressed as Bxx where xx is biodiesel. The most common blend is B20. If the blend was B100 that would mean 100 percent of biodiesel is used. Chemistry has had a tremendous impact on society, ranging from medicines all the way to fuels and batteries. All the things scientists, chemists and other researchers have found through chemistry is crucial to today and how society is run. Fuel cells and all other fuels such as gasoline and diesel fuels have impacted the world in very positive ways.
