Claim 0:
1. A fuel cell module, comprising:
a battery container; and
a plurality of cell members radially arranged inside the battery container, wherein
the battery container includes an inner cylinder having a first double wall structure having a cylindrical first inner wall and a tubular first outer wall arranged radially inside the plurality of cell members, with a first fluid flow path being formed between the cylindrical first inner wall and the tubular first outer wall of the inner cylinder;
the battery container includes an outer cylinder having a second double wall structure having a cylindrical second inner wall and a tubular second outer wall arranged radially outside of the plurality of cell members, a second fluid flow path being formed between the cylindrical second inner wall and the tubular second outer wall of the outer cylinder;
air flowing in the first fluid flow path exchanges heat with a radially inner portion of a cell member of the plurality of cell members, and air flowing in the second fluid flow path exchanges heat with a radially outer portion of the cell member of the plurality of cell members;
a first heat exchange portion, formed by the first fluid flow path and that exchanges heat with the cell member, has a smaller heat transfer area with the cell member than a second heat exchange portion, formed by the second fluid flow path and that exchanges heat with the cell member;
air flowing in the first fluid flow path has a higher flow velocity than air flowing through the second fluid flow path; and
the first fluid flow path and second fluid flow path are configured such that air enters the first fluid flow path, flows through the first fluid flow path to the second fluid flow path, and enters the cell member of the plurality of cell members through a single inlet port.
