摘要： A switching system and control method therefor are provided and implemented with a fuel cell stack system. The switching system enables fuel cell stacks to be connected in series for providing power to a power user while removing the particular disadvantages of a series circuit. In the event of a stack fault, the faulty stack may be bypassed, whereby the remaining stacks provide power to the power user at reduced capacity. The stack is continuously monitored and is reintroduced to the series circuit if the fault clears. If the fault reoccurs a predetermined number of times after the stack has been reintroduced, a “reduced capacity” mode is initiated. Additionally, in the event of a reduced or an increased current demand, stacks are selectively switched in and out of the series connection, for limiting the overall operation voltage range of the fuel cell stack system.

摘要： An apparatus and method for operating a fuel cell power system utilizing a low voltage power source and system power to power an airmover. The fuel cell power system uses a low voltage power source to power the airmover during start-up and transitions to using system power to power the airmover as the fuel cell stack increases its voltage output. During a shutdown operation the fuel cell power system transitions from using system power to using the low voltage power source to power the airmover enabling a purging operation to be performed. A controller coordinates the operation of the airmover between using the low voltage power source and using electrical power produced by the fuel cell stack to power the airmover.
