Estimating the term…
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.
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, a polymer electrolyte membrane disposed between said pair of electrodes, a separator having a flow path for supplying a fuel gas to one of the electrodes and a separator having a flow path for supplying an oxidant gas to the other electrode, said separators being placed on the outer side of said electrodes and said unit cells being stacked with said separators placed therebetween,
