Abstract

A fuel cell housing case includes: a stack case including a first partitioning plate and a second partitioning plate that separate a space in which a fuel cell stack is to be housed from a space in which a boost converter is to be housed; and a pair of stack bus bars provided on both ends in the stacking direction of the fuel cell stack, wherein the first partitioning plate and the second partitioning plate respectively include: slits through which the respective stack bus bars are inserted; and overlapping portions that overlap each other.

First claim

What is claimed is:

1. A fuel cell housing case comprising:
a stack case including a housing, a first partitioning plate and a second partitioning plate that separate a first space in which a fuel cell stack including multiple stacked single fuel cells is to be housed from a second space in which a boost converter disposed above the fuel cell stack is to be housed; and
a first bus bar and a second bus bar respectively provided on both ends in a stacking direction of the fuel cell stack and configured to electrically connect the fuel cell stack to the boost converter,
wherein
the first partitioning plate includes a first insertion portion through which the first bus bar is inserted,
the second partitioning plate includes a second insertion portion through which the second bus bar is inserted, and
the first partitioning plate and the second partitioning plate respectively include a first overlapping portion and a second overlapping portion that overlap each other in a state of being mounted on the stack case;
wherein the first partitioning plate and the second partitioning plate are configured such that the first overlap portion and the second overlap portion overlap by an overlap length that is variable.

2. The fuel cell housing case according to claim 1 , wherein the first overlapping portion and the second overlapping portion are bonded to each other.

3. The fuel cell housing case according to claim 1 , wherein
the first insertion portion includes a first slit, and the first slit is sealed, and
the second insertion portion includes a second slit, and the second slit is sealed.
