Abstract

See full text

Thermal and hydration management systems and methods for fuel cell systems, including control of electrolytic membrane hydration levels. In some embodiments, the thermal properties of the fuel cell are controlled based on a variable associated with the oxidant supply stream and/or a variable associated with the fuel cell energy output. In some embodiments, the temperature of the fuel cell is controlled based on the temperature of the oxidant supply stream. In some embodiments, the temperature range across the fuel cell stack is controlled based on the flow rate of the oxidant stream and the electrical output generated by the fuel cell stack. In some embodiments, the humidity within the fuel cell stack is controlled. In some embodiments, the liquid water content of the cathode exhaust stream is controlled.
