Abstract
A fuel cell module includes a fuel cell stack, and a container that has a frame structure in which a polyhedron is composed of a plurality of main beams, and houses the fuel cell stack. The container has a vertical length and a horizontal length different from each other in side view. At least one main beam among the main beams includes a plurality of fastening points that are arranged along a longitudinal direction of the at least one main beam.
Claims20
A fuel cell module comprising:
- a fuel cell stack;
- a container having a frame structure and including a plurality of main beams forming a polyhedron and including a first reinforcing beam, the container housing the fuel cell stack, and the first reinforcing beam connecting a first main beam and a second main beam among the plurality of main beams;
- and
- a power control unit housed in the container and configured to control the fuel cell stack, wherein:
- the container has a vertical length and a horizontal length different from each other in a side view;
- the first main beam includes a plurality of fastening points that are arranged along a longitudinal direction of the first main beam, the fastening points being configured to fix a bolt that attaches the fuel cell module to an automobile;
- the fuel cell module is attached to the automobile with the bolt at at least one fastening point of the fastening points;
- and
- the power control unit is fixed to the first reinforcing beam.
