FUEL CELL STACK

摘要

A fuel cell stack includes bonding members for joining projecting sections of adjacent frames in cell modules, an inter-cell module seal member forming a seal between the cell modules, and supporting members disposed between adjacent frames in the cell modules. As viewed from above in the direction in which the cell modules are layered, the supporting members overlap at least a part of a section of the inter-cell module seal member that contacts the cell modules.

主权项

1. A fuel cell stack comprising:
a plurality of cell modules, each cell module of the plurality of cell modules comprising at least two layered fuel cell units, each fuel cell unit of the least two layered fuel cell units including a membrane electrode assembly integrally formed with an electrically insulating frame and being sandwiched between a pair of separators; bonding members for joining outer circumferential sections of adjacent frames in the fuel cell units; an inter-cell module seal member disposed between the cell modules and forming a seal between the cell modules; supporting members disposed between the adjacent frames in the cell units, the supporting members overlapping at least a part of a section of the inter-cell module seal member that contacts the cell modules as viewed from above in a direction in which the cell modules are layered; and projecting sections disposed on both sides of the outer circumferential sections of the frame with respect to the layering direction, the bonding member being disposed between the projecting sections, and the supporting members being disposed between frame sections, the frame sections being positioned further inward than the projecting sections.
