The fuel cell is an energy conversion device that produces electricity through the electrochemical reaction of a fuel and oxidative gas. Polymer electrolyte fuel cells, e.g., proton-exchange membrane fuel cells using hydrogen gas as fuel and direct methanol fuel cells, are clean energy sources with .....
