Membrane electrode assembly for a tube-shaped fuel cell and tube-shaped fuel cell

摘要

A membrane electrode assembly ( 11 ) for a tube-shaped fuel cell, which is provided with a tube-shaped solid electrolyte membrane ( 1 ); an outside catalyst electrode layer ( 2 ) formed on an outer peripheral surface of the solid electrolyte membrane ( 1 ); an inside catalyst electrode layer ( 3 ) formed on an inner peripheral surface of the solid electrolyte membrane ( 1 ); an outside collector ( 4 ) arranged on an outer peripheral surface of the outside catalyst electrode layer ( 2 ); and an inside collector ( 5 ) arranged on an inner peripheral surface of the inside catalyst electrode layer ( 3 ), is characterised in that at least one of the outside collector ( 4 ) and the inside collector ( 5 ) is a coiled collector that includes a coiled conductor.
