Summary of the invention
The technical problems to be solved in the utility model provides a kind of compact conformation, microcosmic three-dimensional fuel cell membrane electrode that performance index are high.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of microcosmic three-dimensional fuel cell membrane electrode, comprise proton exchange membrane and be positioned at two surfaces of this proton exchange membrane and with proton exchange membrane surface electrode in contact, its innovative point is: described proton exchange membrane has at least a surface to adopt concavo-convex profile structure; Described two electrodes all adopt the profiling profile structure that can fully contact with the surface of side proton exchange membrane separately.
Further, the concavo-convex profile structure of described proton exchange membrane is to be raised or sunken that lattice-like distributes.
Further, the concavo-convex profile structure of described proton exchange membrane is the whole waveform that presents.
Further, described concavo-convex profile structure concave, projection are 10 ~ 20um apart from the height of proton exchange membrane datum level.
Advantage of the present utility model is: proton exchange membrane has at least a surface to adopt concavo-convex profile structure; Two electrodes all adopt profiling profile structure correspondingly, and then are realizing on proton exchange membrane surface and the basis that electrode fully contacts the circulation area of increase electric current in limited space.
