Abstract:
1. A power generator comprising: a fuel cell stack; a gas flow loop having an input of oxygen containing ambient air and flowing through the fuel cell stack to provide oxygen containing air to the fuel cell stack and to provide a carrier gas to cool and remove water from the fuel cell stack, the gas flow loop including a temperature sensor and a humidity sensor; a hydrogen generator coupled to the gas flow loop to receive water vapor from ambient air introduced into the gas flow loop and water vapor generated by the fuel cell stack and to provide hydrogen to the fuel cell stack; and a controller coupled to the gas flow loop to separately control airflow past the fuel cell stack based on temperature information received from the temperature sensor and control water vapor provided to the hydrogen generator based on humidity information received from the humidity sensor.
