1 McGehee structures are housed in a hydrogen fuel cell, and can be stacked side by side to generate a large amount of electricity, seen in figure 1.1, which illustrates visually how a hydrogen fuel cell vehicle works(Consumer Energy Center). On the positively charged anode part, or left side, pressurized hydrogen gas enters where it will remain until it comes into contact with the catalyst. When the hydrogen gas comes into contact with the catalyst, which is comprised of a platinum plate, the hydrogen gas is then split into two positive hydrogen atoms, and two negatively charged electrons. These electrons given off by the hydrogen gas get routed to an external circuit, which in return powers the vehicle. After turning an electric motor, these electrons return to the cathode side of the hydrogen fuel cell. This reaction is what causes electricity out of the hydrogen fuel cell, and generates around 0.7 volts of electricity(Jacobson). With a large number of hydrogen cells, a great deal of current can be produced to power the automobile. Next, on the cathode side of the hydrogen fuel cell, oxygen gas is being forced through until it reaches the catalyst. When coming into contact with the
