Abstract
A fuel cell system includes a fuel cell stack and at least one electrical energy storage device that can be electrically connected to and/or disconnected from the fuel cell stack by at least one electronic switching element which is based, for example, on a MOSFET. The fuel cell stack itself is cooled. The at least one switching element is in thermally conductive contact with a cooling circuit for cooling the fuel cell stack, for example, by mounting the switching element on the end plates of the fuel cell stack.
