초록

A polymer electrolyte membrane fuel cell includes an anode chamber and a cathode chamber which are separated by the electrolyte membrane. The fuel cell directly oxidizes a liquid methanol fuel which is fed into the anode chamber from a liquid methanol storage container. The liquid methanol is mixed with water in the anode chamber, and the mixture passes into and through the electrolyte membrane. Some of the methanol and water pass through the membrane into the cathode chamber and into a process air stream which moves through the cathode chamber. The meth...
