Abstract
The specification discloses a fuel cell comprising stacked unit cells, each of the unit cells including a pair of electrodes having a catalytic reaction layer and a gas diffusion layer, an electrolyte layer disposed between the pair of electrodes, a separator having a flow path for supplying a fuel gas to one electrode and a separator having a flow path for supplying an oxidant gas to the other electrode, the separators being placed on the outer side of the electrodes and the unit cells being stacked with the separators placed therebetween, wherein at least the catalytic reaction layer, the gas diffusion layer or the flow path has water-repelling properties. Thereby, a fuel cell having a superior cell performance is obtained.
