Abstract
Official abstract text for this publication.
Provided is a fuel cell system which includes a fuel cell that generates electric power by electrochemical reaction between hydrogen gas and oxidizing gas, and a fuel cell case that houses the fuel cell. A more fragile portion compared to the rest of the fuel cell case in terms of strength is provided in the fuel cell case along an outline of a given shape so that a depressurizing opening having the given shape is formed when internal pressure of the fuel cell case becomes higher than given pressure.
First claim
Opening claim text (preview).
What is claimed is: 1 . A fuel cell system comprising: a fuel cell that generates electric power by electrochemical reaction between hydrogen gas and oxidizing gas; and a case that houses the fuel cell, wherein a more fragile portion compared to a portion of the case other than the more fragile portion in terms of strength is provided in a specific surface of the case along an outline of a given shape so that a depressurizing opening having the given shape is formed when internal pressure of the case becomes higher than given pressure. 2 . The fuel cell system according to claim 1 , wherein the specific surface is, among surfaces of the case, a surface adjacent to an object arranged outside the case. 3 . The fuel cell system according to claim 1 , wherein the fragile portion is formed in the specific surface of the case along three sides of a rectangular shape so that the depressurizing opening having the rectangular shape is formed when internal pressure of the case becomes higher than the given pressure. 4 . An under hood structure of a vehicle, comprising: a fuel cell that generates electric power by electrochemical reaction between hydrogen gas and oxidizing gas; a case that houses the fuel cell; and an object that is arranged outside the case and adjacent to a specific surface of the case, wherein a more fragile portion compared to a portion of the case other than the more fragile portion in terms of strength is provided in the specific surface of the case along an outline of a given shape so that a depressurizing opening having the given shape is formed when internal pressure of the case becomes higher than given pressure.
