Abstract
A fuel cell system includes a fuel cell stack, an enclosure housing the fuel cell stack and a blower. The blower is located inside the enclosure and is adapted to draw air from inside the enclosure to produce an air flow through the fuel cell stack and establish a negative pressure inside the enclosure with respect to a region outside of the enclosure.
