NOVELTY - The membrane electrode assembly (100) has a first electrode layer (1) and a second electrode layer (4) provided at one side and other side of a solid electrolyte layer (2), respectively. The solid electrolyte layer is formed from division bodies (2a). An insulation belt (6) is provided between division bodies and relieves the deformation to surface direction of division bodies. The insulation belt has electrical insulation layer (4) and shield layer (3) that shields between the division bodies.    USE - Membrane electrode assembly for fuel cell (claimed) used for mobile body such as motor vehicle.    ADVANTAGE - The crack caused by thermal stress of solid electrolyte layer is prevented effectively since large deformation does not arise or thermal stress does not concentrate in the solid electrolyte layer by absorbing the differential thermal expansion in the insulation belt even if the coefficients of thermal expansion of solid electrolyte layer and electrode layers differ. The damage to membrane electrode assembly is prevented since cushioning properties are increased and vibration and impact are absorbed by adopting metal porous body having porosity of 98 percent or more.    DETAILED DESCRIPTION - The insulating layer is formed from insulating oxide ceramics having thermal expansion coefficient substantially the same as zirconia and zirconia, or glass containing zirconia adhesive agent. The shield layer is formed from gold, silver, copper, platinum, nickel, iron, cobalt, lanthanum, strontium, manganese, alloy containing gold, silver, copper, platinum, nickel, iron, cobalt, lanthanum, strontium, manganese, or glass. The first electrode layer is formed from gold, silver, platinum, palladium, nickel, iron, cobalt, lanthanum, strontium or alloy containing at least one or more types of element selected from the element groups consisting of manganese or cermet which is a mixture of at least one or more types of element and solid electrolyte material selected from the element groups. An INDEPENDENT CLAIM is included for a manufacturing method of the membrane electrode assembly.
