METHOD OF MAKING MEMBRANE ELECTRONIC COMPONENT AND REINFORCED ELECTROLYTIC MEMBRANE IN FUEL CELL WITH POLYMER ELECTROLYTE, AND MEMBRANE ELECTRODE ASSEMBLY AND REINFORCED ELECTROLYTIC MEMBRANE MADE USING SAID METHOD Russian patent published in 2010 - IPC H01M8/10 H01M8/02 

FIELD: chemistry.

SUBSTANCE: invention relates to fuel cells with polymer electrolyte. According to the invention, a membrane electrode assembly (MEA) A in a fuel cell with polymer electrolyte is made in a state when there is no boundary between an electrolytic membrane (1) and an electrode catalyst bed (6). Electrolyte particles (2), fine electrolyte particles (3), and electrode catalyst particles (4) of their mixture (5) are deposited on a porous reinforced membrane, forming a layered body (10Ã). Electrolyte particles (2) and fine electrolyte particles (3) are molten by heating the layered body (10Ã) between heating plates (21) and (22), and the porous reinforced membrane is heated by molten electrolyte, forming a reinforced electrolytic membrane. Also the reinforced electrolytic membrane and the electrode catalyst bed (6), which includes electrode catalyst particles (4), are bonded into an agglomerate owing to the molten electrolyte in a state when there is no interlayer boundary, that way forming a membrane electrode assembly.

EFFECT: increased electrical efficiency.
