Patent Images
1. A fuel cell system comprising:
- a first fuel cell stack;
a second fuel cell stack with lower output voltage than the first fuel cell stack, a pre-switching stack configured by the first fuel cell stack or the second fuel cell stack, a step-up stack configured by the first fuel cell stack or the second fuel cell stack, a post-switching stack configured by at least the first fuel cell stack; and
an electricity control device configured to step up voltage of the step-up stack with the pre-switching stack connected to a load and then switch to a connection state where the post-switching stack is connected to the load.
