摘要： An electrode for fuel cells includes several consecutive layers of electrically conductive porous material. The consecutive layers include recesses which form sections of flow channels. Within the individual layers, however, the channels are not continuous. When the consecutive layers are combined, the channel sections of the various layers, which are disposed in such a way that there are overlaps between them, complement one another to form a complete fluid-distributor structure. A distribution of fluid also takes place in the thickness direction of the electrode by virtue of the fact that the flow channels pass over repeatedly from one layer into the other, besides the distribution of fluid in a plane. A composite structural unit for fuel cells and a polymer-electrolyte-membrane fuel cell, are also provided.

摘要： This invention relates to electrode substrates for electrochemical cells, particularly low-temperature fuel cells, and processes for their production. Low-cost carbon fiber paper structures are used as precursor for preparation of an all-carbon product that has a high electric conductivity and porosity and can be processed in a continuous reel-to-reel mode. These paper materials are further impregnated and processed to adjust the final product properties. This all-carbon electrode substrate is not brittle thereby avoiding the main disadvantage of the prior art.
