Abstract
A fuel cell utilizing parallel flow of a hydrogen stream, an oxygen stream, and an electrolyte solution with respect to the electrodes, while maintaining mechanical support within the fuel cell. The fuel cell utilizes framed electrodes to maintain a high air flow rate and low pressure throughout the fuel cell. The fuel cell is also designed to maintain mechanical support within the fuel cell while the electrodes expand and contract in response to the absorption of oxygen and hydrogen. Gas is predistributed by the compression plates and frames to supply the electrodes with high concentrations of oxygen from air.
