The new power control algorithm to improve freeze startability of the TOYOTA FCHV-adv is reviewed in this paper. This new algorithm is using the inherent capacitance characteristics of the fuel cell in order to adjust the output power response of the fuel cell to the target power of the vehicles. The algorithm is combined with fuel cell operation method to warm rapidly, called Rapid Warm-Up Operation. This operation is based on: concentration overvoltage increase and conversion efficiency decrease by limiting oxygen or hydrogen supply. As a result, the FCHV-adv has been capable of starting at a temperature of -30℃.
