| 摘要 |
In one embodiment, an electric power plant comprises an array of fuel cell systems, the fuel cell systems each comprising a regenerative fuel cell stack, an oxidant supply system for supplying an oxidant gas to the stacks, a fuel supply system for supplying a fuel gas to the stacks, a system for supplying a humidified carrier gas to the stacks, a DC current supply system for connecting a power source across the stacks, and a storage system for storing hydrogen received from the stacks. In power generation mode, the fuel cells of the present power plant generate electricity for supply to one or more electrical loads. In electrolysis mode, the stacks generate hydrogen from a humidified carrier gas stream.
