Abstract

In a fuel cell housing structure, an electrically insulated housing contains a fuel cell, and is arranged to provide a space within the housing surrounding the fuel cell. A vent gas intake port and a vent gas exhaust port are provided in the housing. At least one of the vent gas intake port or vent gas exhaust port connects to the space at a position either above or on the same level as the fuel cell. A blocking member, which is also electrically insulated from the fuel cell, blocks water, entering the housing from at least one of the ports, from contact with the fuel cell.
