Fuel cell stack for hydrogen fuel power generator

摘要

A flexible fuel cell stack is also described that includes an anode electrode layer, an adhesive and anode gas diffusion layer coupled to the anode electrode layer, an ion exchange membrane coupled on a first side to the gas diffusion layer opposite the anode electrode layer, an adhesive and cathode gas diffusion layer coupled to a second side of the ion exchange membrane, and a cathode electrode layer coupled to the adhesive and cathode gas diffusion layer opposite the ion exchange membrane. The fuel cell stack may be incorporated into a power generator that includes a hydrogen producing fuel.

1. A fuel cell stack comprising:
an anode electrode layer comprising an anode electrode portion and an anode electrode frame; an anode double sided adhesive layer having a non-adhesive anode gas diffusion layer in an opening therein, said double sided adhesive layer adhered on one side to the anode electrode frame such that a portion of the anode electrode is in contact with the anode gas diffusion layer; an ion exchange membrane layer having an ion exchange membrane in an opening therein, said ion exchange membrane aligned with the non-adhesive anode gas diffusion layer in the opening in the anode double sided adhesive layer, said ion exchange membrane layer adhered on a first side to the side of the anode double sided adhesive layer opposite the anode electrode layer; a cathode double sided adhesive layer having a non-adhesive cathode gas diffusion layer in an opening therein, said cathode gas diffusion layer aligned with the ion exchange membrane, said double sided adhesive layer adhered on one side to a second side of the ion exchange membrane; and a cathode electrode layer comprising a cathode electrode portion and a cathode electrode frame adhered to the cathode double sided adhesive layer having a non-adhesive cathode gas diffusion layer in an opening therein, on the side opposite the ion exchange membrane, such that a portion of the cathode electrode is in contact with the cathode gas diffusion layer; wherein each of the layers are adhered together as parallel adjacent planes rolled to form a gas tight cylindrical flexible fuel cell stack adhered around a rigid cylindrical support.
