The fuel cell has several advantages including high overall energy efficiency, good environmental compatibility, less restriction and thus is expected to be a new energy source in the coming generation. Polymer Electrolyte Fuel Cell (PEFC) is expected as the power source of the transportation of vehicle because of its high output density and the availability at a normal temperature. The hot-press method is the most common for PEFC, for sticking electrodes with on electrolyte membrane. However, it is confirmed experimentally this method needs water to be held in the electrolyte membrane of the cell. This present paper describes the new trial production with gellike electrolyte for fuel cell. As the results of this trial production, it was shown that this method was effective for water holding. Also, it is clear that from estimating the equivalent circuit constants experimented by addition of step current, ionic transfer resistance declines with temperature raise and on the high current density increase of electric charge transfer resistance shows concentration polarization.
