Zusammenfassung:PROBLEM TO BE SOLVED: To provide a method for conditioning, in an optimal temperature range, a membrane electrode assembly laminated with a membrane polymer electrolyte matrix, to improve its efficiency.SOLUTION: A membrane electrode assembly contains two electrodes, and one membrane polymer electrolyte matrix which contains an oxo acid of phosphorus and/or sulfur and a polymer having at least one heteroatom selected from the group consisting of nitrogen, oxygen and/or sulphur. In the method, after the polymer electrolyte matrix and the electrodes are laminated to form the membrane electrode assembly, the membrane electrode assembly is conditioned in a temperature range from 60°C to 300°C, thereby allowing increase in output.
