Pressurization air systems in a multimodule fuel cell power plant are interconnected to provide improved power plant operating efficiency at part load. Each power generation module air pressurization subsystem has its own turbocompressor to provide a compressed air supply to its own power generation subsystem at rated power plant load. When load demand on the power plant is reduced, some of the turbocompressors in the interconnected power generation modules in the plant are shut off. The interconnecting valves are opened so that the remaining turbocompressors can supply all of the compressed air needed by all of the power generation subsystems in the interconnected power generation modules. |
