Title:
METHODS OF PRODUCING REINFORCED ELECTROLYTE MEMBRANE AND MEMBRANE ELECTRODE JOINT BODY
Document Type and Number:
WIPO Patent Application WO/2007/148805
Kind Code:
A1
Abstract:
A reinforced electrolyte membrane obtained by directly impregnating molten
electrolyte resin into a porous reinforced membrane is produced by a simple method.
A membrane electrode joint body provided with a reinforced electrolyte membrane
is simply produced by slightly modifying the method of producing a reinforced
electrolyte membrane. Heated/molten electrolyte resin (p) is extruded from
the resin outlet (3) of a die (2), and porous reinforced membranes (6) are fed into
the extruded molten electrolyte resin (p). The porous reinforced membranes
(6) fed by two oppositely-arranged heated rotary rolls (4) are embedded into
molten electrolyte resin (p) to allow the resin (p) to impregnate into the membranes
(6), thereby forming a reinforced electrolyte membrane (20). When the surfaces
of the rotary rolls (4) are coated with electrode catalyst particles (31), a membrane
electrode joint body (40) provided with a reinforced electrolyte membrane (20)
can be formed.
