Profit application, just discloses a kind of pile for being not provided with bipolar plates, has solid polymer dielectric film and clamps the polymer
A pair of catalyst layers of dielectric film.The layered product of solid polymer dielectric film and catalyst layer is entered by a pair of gas diffusion layers
One step clamps.Adjacent catalyst layer and gas diffusion layers form gas-diffusion electrode.Solid polymer dielectric film and a pair
Gas-diffusion electrode is further with laminated state constituting membrane electrode assembly（MEA）.MEA is further clamped by a pair of barrier films.Should
Barrier film obtains in the following manner：Punch forming process is applied on the thin plate below thickness 0.5mm, be shaped to bumps
Shape.The convex portion for the barrier film observed from MEA sides contacts with MEA.The recess for the barrier film observed from MEA sides is used as
Gas is by using gas passage during fuel cell operation.In the disclosure, including electrolyte membrane layer, catalyst layer, gas
Diffusion layer and outermost barrier film, although wherein be not provided with bipolar plates, no matter but barrier film from shape functionally
All it is consistent with bipolar plates role, alleviates some weight compared to bipolar plates, but still occupy certain weight and body
Product, can not tackle the problem at its root.
