Claims

[Scope of utility model registration request]

(1) Single cells consisting of fuel and oxidant electrodes each having a reactant gas flow path on one side and a catalyst layer on the other side, and an electrolyte matrix placed between the catalyst layers of both electrodes are stacked with flat plate separators in between. In the fuel cell, at least one of the two electrodes has an end parallel to the reactant gas flow path made of an air-impermeable material;
A fuel cell comprising this air-impermeable material and an elastic body disposed between the flat separators.

(2) The fuel cell according to claim 1, wherein the gas-impermeable material is provided with a protrusion for preventing movement of the elastic body.

(3) Utility model registration claim 1, characterized in that the flat plate separator is provided with projections for preventing movement of the elastic body.
Fuel cell as described in Section.
