摘要： A highly reliable polymer electrolyte fuel cell includes an anode-side separator plate and a cathode-side separator plate that are provided with an anode-side sealing member and a cathode-side sealing member, respectively. The anode-side and cathode-side sealing members seal the cell in cooperation with a polymer electrolyte membrane at sealing parts where the anode-side and cathode-side sealing members are opposed to each other, thereby preventing gas from leaking out of gas flow channels. One of the anode-side and cathode-side sealing members has a pointed rib that comes in contact with the sealing parts in a linear manner, and the other sealing member comes in contact with the sealing parts surface to surface.

摘要： The invention relates to a separator plate for use in a fuel cell and to a fuel cell. The separator plate has: a passage groove group including a plurality of gas passage grooves 35 formed so as to extend in serpentine form; and a communicating groove 33 configured to provide fluid communication between adjacent portions of the gas passage grooves. Various separator plates have heretofore been disclosed in public by many documents and the blockage of the gas passage grooves caused by condensed water droplets formed therein is deemed to be properly prevented. However, the inventors think that those separator plates have a critical oversight in the behavior of a gas-liquid two phase fluid including a reaction gas and condensed water. That is, the condensed water is likely to concentrate in the vicinity of the gas passage grooves located in the downstream side of such separator plates and therefore these separator plates are liable to blockage. The invention intends to overcome the above problem by making the communicating groove 33 shallower than the gas passage grooves.
