Title:
REVERSIBLE FUEL CELL AND REVERSIBLE FUEL CELL SYSTEM
Document Type and Number:
WIPO Patent Application WO/2013/145468
Kind Code:
A1
Abstract:
A reversible fuel cell comprises: a positive electrode including manganese dioxide; a negative electrode including a hydrogen-occluding material; a separator interposed between said positive electrode and said negative electrode; an oxygen storage chamber and a hydrogen storage chamber that respectively independently store hydrogen generated by said positive electrode and oxygen generated by said negative electrode; and an electrolyte. Said negative electrode and said positive electrode are electrodes for power generation and are electrodes that electrolyse said electrolyte using current supplied from outside. Also, said oxygen storage chamber is filled with said electrolyte in which oxygen is dissolved. This fuel cell is capable of converting to gas electrical energy supplied in the event of overcharging and is capable of re-converting this to electrical energy for utilisation. A reversible fuel cell and fuel cell system are therefore provided having an excellent energy utilisation efficiency, energy density and load tracking capability.
