How does a hydrogen fuel cell work in automobiles?
There are many types of fuel cells, but the one that is being considered for powering automobiles is called the polymer exchange membrane fuel cell. One of the benefits of this type of fuel cell is that it has a low operating temperature. It wouldn’t take very long for the fuel cell to become heated enough to produce the electricity needed to power an automobile. A polymer exchange membrane fuel cell has four main parts. The catalyst is what makes hydrogen and oxygen react with each other. The proton exchange membrane, or electrolyte, acts as a block for electrons. The anode and cathode are the negative and positive posts of the fuel cell, respectively.
