APPARATUS AND METHOD FOR FUEL CELL STANDBY

摘要

An apparatus for placing a fuel cell stack in a standby mode is provided. The apparatus comprises a compressor, a fuel cell stack, a cathode valve and a controller. The compressor is operably coupled to an air induction system for providing a cathode stream. The fuel cell stack provides electrical power to a load in response to the cathode stream. The cathode valve is operably coupled to an outlet of the fuel cell stack for controlling a flow of the cathode stream to the fuel cell stack. The controller is configured to receive a power request amount for the load and to compare the power request amount to a predetermined amount. The controller is further configured to control the compressor to operate at a minimum speed and the cathode valve to close in response to determining that the power request amount is similar to the predetermined amount
