Abstract
A fuel cell includes (i) a membrane electrode assembly, (ii) a sealing frame surrounding the membrane electrode assembly, (iii) a manifold portion configured to supply and discharge reactant gas, and (iv) bipolar plates arranged on both sides of the membrane electrode assembly and the sealing frame and having a gas distributing structure configured to distribute the reactant gas onto the membrane electrode assembly. The sealing frame has a gas flow channel extending from the manifold portion in a main extension plane of the fuel cell to the gas distributing structure of the bipolar plates. The gas flow channel has a shape with a winding path, at least partially, in the main extension plane. Also disclosed is a corresponding method for manufacturing a fuel cell that is capable of reducing deformation of the sealing frame in the perpendicular direction and avoiding collapse of the gas flow channel, while preventing a significant drop in gas pressure.
