Abstract
A highly efficient fuel cell capable of reasonably and effectively utilizing an internal reforming reaction is obtained even when an anode layer provided in a fuel cell element has a thickness of several tens of micron order. A fuel cell single unit is configured to include a reducing gas supply path for supplying a gas containing hydrogen to an anode layer, a steam supply path for supplying steam generated in a fuel cell element to the reducing gas supply path, and an internal reforming catalyst layer for producing hydrogen from a raw fuel gas by a steam reforming reaction are provided in the fuel cell single unit, and at least one steam supply path is provided on an upstream side of the internal reforming catalyst layer in a flow direction of the reducing gas supplied to the anode layer.
