Like batteries, fuel cells generate electricity without any rotary motions or combustion being involved. They utilize electrochemical reaction in production of electricity. The electrochemical reaction brings together hydrogen ions and oxygen atoms together. Unlike batteries, they rely of external fuel sources (hydrogen) to continuously produce power (Science Applications International Corporation 39). They utilize two electrodes, an anode and a cathode to form a complete and operational cell. The electrodes are sandwiched around specific electrolytes. A catalyst is also availed to ensure accelerated electrochemical reaction. The figure attached illustrates the working technique of a fuel electrode see appendix 1).
