Abstract
In a fuel cell in which an electrode and a separator are stacked together, a rib which is provided on the separator and forms a reaction gas flow path is fixed to an electrode by a liquid sealant, and the porosity of a portion of the electrode which has been impregnated with the liquid sealant is lower than the porosity of another portion of the electrode. In order to store surplus liquid sealant, the separator may also have a liquid sealant storage portion that is depressed in the thickness direction from the top of the rib.
