【Abstract】 With the aid of a computer-controlled electronic load, the effects of the cell temperature on the transient performance of a direct methanol fuel cell were studied experimentally. The dynamic response of the cell to the variable cell temperature was also explored. The steady-state performance of the cell increases with cell temperature. The responses of the cell to dynamic loads become quicker and more stable at higher temperature. At constant voltage, the transient current of the cell to changeable cell temperatures during increasing temperature is higher than that during decreasing temperature.更多还原
