摘要： Various systems and methods disclosed herein may include a fuel cell system that may dynamically respond to changes in steam concentration in the fuel cell system. The fuel cell system may include a fuel cell stack that produces an anode exhaust stream, an anode recycle blower that receives the anode exhaust stream and outputs an anode recycle stream, and a humidity sensor configured to measure the steam concentration of the anode recycle stream. The fuel cell system may also include a master controller configured to receive steam concentration measurement from the humidity sensor and control the operation of the anode recycle blower and/or other components based on the steam concentration measurement.

摘要： A method for operating a fuel cell system includes drawing a base level DC electric energy from a first fuel cell of a first type to a combined DC bus, measuring a DC voltage at the combined DC bus, determining whether the DC voltage at the combined DC bus falls short of a DC voltage threshold, and drawing a variable DC electric energy from a second fuel cell of a second type different from the first type in response to determining that the DC voltage at the combined DC bus falls short of the DC voltage threshold.
