Abstract
A release outlet () of a release pipe () of a relief valve () is provided in the vicinity of an exhaust outlet () of a fuel cell box () in a space between a sub-frame () and the fuel cell box (). A ventilating inlet () is formed on a front wall () of the fuel cell box (). A fan () can send outside air into the fuel cell box (). A ventilation flow of the outside air which is sent into the fuel cell box () passes through and ventilates the fuel cell box () so as to cool a fuel cell stack (). Exhaust air is exhausted rearward from the exhaust outlet () of an exhaust duct (). The release pipe () and the release outlet () are heated by the exhaust air. Therefore, heating the release pipe () and the release outlet () can prevent the release outlet () from being blocked by snow or ice.
