초록 ▼

A regenerative fuel cell assembly is provided in which a fuel cell is integrated with an electrolysis cell. In a preferred embodiment the fuel cell assembly and electrolysis cell assembly are spaced apart and have their hydrogen electrodes in facing relationship; a water transport matrix is disposed in the space between the hydrogen electrodes, and a water storage matrix is disposed adjacent the oxygen electrode of the fuel cell. During operation of the fuel cell the water storage matrix holds the water produced by the fuel cell; during electrolysis cell operation the water in the water storage matrix passes to the water transport matrix which carries it to the electrolysis cell where it is consumed.

대표청구항 ▼

A regenerative fuel cell system which operates on hydrogen and oxygen, comprising: a housing: a first assembly disposed in said housing including a fuel cell having a hydrogen electrode, a first oxygen electrode and an electrolyte matrix disposed therebetween, and including a first oxygen passage in fluid communication with said first oxygen electrode, said first oxygen electrode being composed of a first material; a second assembly disposed in said housing including an electrolysis cell having a hydrogen electrode, a second oxygen electrode and an electrolyte matrix disposed therebetween, and including a second oxygen passage in fluid communication with said second oxygen electrode, said second oxygen electrode being composed of a second material different from said first material, said fuel cell hydrogen electrode and said electrolysis cell hydrogen electrode being spaced apart and in facing relationship; a water matrix disposed in the space between and in contact with said fuel cell hydrOgen electrode and said electrolysis cell hydrogen electrode and including portions bridging said hydrogen electrodes for transporting water produced by said fuel cell during fuel cell operation to said electrolysis cell for use during electrolysis cell operation, said water matrix shaped to define hydrogen passages in communication with said fuel cell hydrogen electrode and said electrolysis cell hydrogen electrode, said first assembly having a water storage matrix associated with one of said fuel cell electrodes for storing water produced by said fuel cell during fuel cell operation, said water storage matrix being adjacent said first oxygen electrode of said fuel cell and in fluid communication with said water matrix; fluid connecting means in communication with said hydrogen passages and said oxygen passages for providing hydrogen to said hydrogen passages and oxygen to said oxygen passages, and including seal means preventing said hydrogen passages from communicating with said oxygen passages; and means for operating said first assembly always as a fuel cell and said second assembly always as an electrolysis cell, said means being in electrical communication with said assemblies.
