Abstract:
Membrane-membrane stiffening member union (1) comprising polymer electrolyte
membrane (10) having paired first main surface (F1) and second main surface (F2)
opposite to each other and having substantially a rectangular shape; a pair of
first membrane stiffening members (22,24) of membranelike configuration disposed
on regions along set of sides opposite to each other among four sides of the first
main surface (F1) and having main surfaces smaller than the first main surface
(F1); and a pair of second membrane stiffening members (26,28) of membranelike
configuration disposed on regions along set of sides opposite to each other among
four sides of the second main surface (F2) and having main surfaces smaller than
the second main surface (F2), wherein the pair of first membrane stiffening members
(22,24) and the pair of second membrane stiffening members (26,28) are arranged
so as to as a whole extend along the four sides of the polymer electrolyte membrane
(10) and to pinch four corner portions of the polymer electrolyte membrane (10).
