FUEL CELL SYSTEM

Abstract:

A fuel cell system mounted on a vehicle includes a fuel cell stack and a stack case. In the stack case, an inflow hole structure is formed on a lower portion of a front end surface facing forward in the traveling direction of the vehicle. An outflow hole structure is formed on an upper portion of the front end surface. Air around the stack case enters the inside of the stack case from the inflow hole structure. Air exiting from the inside of the stack case passes through the outflow hole structure. The opening area of the outflow hole structure is larger than the opening area of the inflow hole structure.
