Abstract
A fuel cell provides for rapid pressure equalization across the proton exchange membrane by means of an expansion chamber on one side of the proton exchange membrane, the expansion chamber communicating with the gas on the other side of the membrane. Changes in size of the expansion chamber adjust pressure more rapidly than external control of flow rates.
