Abstract
A method for starting operation of a solid polymer fuel cell from a temperature below 0° C. is disclosed that prevents certain problems with ice formation as the fuel cell thaws. During startup, the method involves providing the volumetric oxidant flow at a rate less than two thirds of its maximum when the coolant temperature is near 0° C.
