摘要 |
The present invention relates to a fuel cell with protective device, comprising a plurality of fuel cell stacks, a fuel cell protection circuit unit and a switch control device. The fuel cell protective circuit unit consists of a plurality of channel selection devices and a series-parallel circuit unit. The channel selection devices respectively correspond to one of the fuel cell stacks. The series-parallel circuit unit is electrically connected to the channel selection devices and has an electric output terminal. The fuel cell stacks are respectively electrically connected to the corresponding channel selection devices in the fuel cell protection circuit unit, and the switch control device controls the selection by the corresponding channel selection devices of an electrically open state or an electrically closed state between respective fuel cell stack and the series-parallel circuit unit.
