Mount structure for fuel cell stack

摘要

A mount structure includes side mounts for holding a fuel cell stack to thereby fix the fuel cell stack to first vehicle frames, and rear mounts for fixing the fuel cell stack to a second vehicle frame. The strength of the side mounts is lower than the strength of the rear mounts. In the structure, when an external load is applied to a fuel cell electric vehicle, the side mounts are broken prior to breakage of the rear mounts.

主权项

1. A mount structure for mounting a fuel cell stack in a fuel cell vehicle, the fuel cell stack being formed by stacking a plurality of fuel cells for generating electrical energy by electrochemical reactions of a fuel gas and an oxygen-containing gas,
wherein the fuel cell stack includes side mounts at both ends in a vehicle width direction, and a rear mount on a rear side in a vehicle longitudinal direction; the fuel cell vehicle has first vehicle frames to which the side mounts are fixed, and a second vehicle frame provided below the fuel cell stack and to which the rear mount is fixed; and a strength of the side mounts is lower than a strength of the rear mount such that the side mounts are broken prior to breakage of the rear mount when an external load is applied to the fuel cell vehicle.
