A fuel cell module includes a container and a plurality of cell members radially arranged inside the container. Inside the container, a first fluid flow path through which a first fluid that exchanges heat with an inner portion of the plurality of cell members flows is formed, and a second fluid flow path through which a second fluid that exchanges heat with an outer portion of the plurality of cell members flows is formed. A first heat exchange portion that forms the first fluid flow path and exchanges heat with the cell member has a smaller heat transfer area with the cell member than a second heat exchange portion that forms the second fluid flow path and exchanges heat with the cell member. The first fluid having a larger temperature difference with the cell member than the second fluid flows in the first fluid flow path.

Fuel cell module

A fuel cell system includes a fuel cell, a fuel gas supply line, an oxidizing agent gas supply line, a fuel gas discharge line, and a reformer provided in the fuel gas supply line. A first circulating line circulates the fuel gas from the fuel gas discharge line to an upstream side of the reformer in the fuel gas supply line as a first circulating gas. The circulation device is provided in the fuel gas supply line, and suctions the first circulating gas by using the flow of the fuel gas flowing through the fuel gas supply line as a driving flow. A second circulating line circulates the fuel gas from a downstream side of the circulation device in the fuel gas supply line or the fuel gas discharge line to the upstream side of the circulation device in the fuel gas supply line as a second circulating gas.
