Process for making a fuel cell with cylindrical geometry

摘要

The invention relates to a process for production of an electrode-membrane-electrode assembly on a cylindrical substrate (1), characterized in that the electrode-membrane-electrode assembly is made by successively depositing an electrode layer (2, 3), a membrane layer (4) and an electrode layer (5, 6) around the said cylindrical substrate, the said substrate being composed of a material that can be totally or partially eliminated during an elimination step at the end of the said process. The invention also relates to an electrode-membrane-electrode assembly obtained by the said process and a fuel cell comprising at least one such electrode-membrane-electrode assembly.
