Abstract
A fuel cell module can prevent excessive extending of crack in a cleavage part when the cleavage part cleaves to reduce internal pressure of the housing that stores the fuel cell stack and can prevent the exposure of a high-voltage part inside of the housing. The fuel cell module includes a fuel cell stack and a housing that stores the fuel cell stack. The housing includes a partition wall, a cleavage part on the partition wall that cleaves when the internal pressure of the housing increases to a predetermined pressure, a high-rigidity part on the partition wall to surround the cleavage part, and a plurality of elongated protrusions on the partition wall outside of the high-rigidity part. The strength of the cleavage part is lower than the elongated protrusions and the strength of the high-rigidity part is higher than the elongated protrusions and can prevent extension of a crack in the cleavage part.
