Abstract:
A fuel cell comprising:at least one hydrogen electrode frame having an inner side and an outer side, wherein a hydrogen electrode is disposed within said inner side of said hydrogen electrode frame and a compression plate is disposed within said outer side of said hydrogen electrode frame; at least one oxygen electrode frame having an inner side and an outer side, wherein an oxygen electrode is disposed within said inner side of said oxygen electrode frame and a compression plate is disposed within said outer side of said oxygen electrode frame; at least one electrolyte chamber disposed between said hydrogen electrode and said oxygen electrode; said compression plate disposed within said hydrogen electrode frame being configured to distribute a hydrogen stream across said hydrogen electrode; said compression plate disposed within said oxygen electrode frame being configured to distribute an oxygen containing stream across said oxygen electrode; said inner sides of said hydrogen electrode frame and said oxygen electrode frame being adhered together forming a series of electrolyte flow channels disposed between said hydrogen electrode frame and said oxygen electrode frame, and a plurality of electrolyte flow distributing structures disposed within said electrolyte flow channels, said series of electrolyte flow channels and said electrolyte flow distributing structures being configured to uniformly distribute an electrolyte solution laterally through said electrolyte chamber.
