Types of Fuel Cells
PEMs are exceptionally responsive to varying loads (such as driving) and are increasingly cheap to manufacture. The PEM fuel cell uses an advanced plastic electrolyte (typically Nafion) to shuttle protons from the anode to the cathode. The PEM's solid electolyte is much easier to handle and use than a liquid counterpart, and its low operating temperature allow ...
