Abstract
An electrochemical device capable of improving arrangement efficiency of bonded bodies and securing favorable sealing characteristics is provided. An electrolyte membranehas a reaction regionA sandwiched between a fuel electrodeand an oxygen electrodeand a peripheral regionB exposed from between the fuel electrodeand the oxygen electrode. A connection memberhas a bent sectionbetween two flat sectionsand. Since an adhesive layeris provided in the peripheral sectionB of the electrolyte membrane, and the bent sectionof the connection memberis bonded to the adhesive layer, arrangement efficiency of a bonded bodyis improved, and favorable sealing characteristics are secured. The adhesive layerhas a structure in which a first contact layer having high adhesion to the electrolyte membrane, a barrier layer, a strength retention layer, and a second contact layer having high adhesion to the connection memberare sequentially laminated. Since a connection-member-side adhesive layer is provided on the bent sectionof the connection member, adhesion strength can be further improved.
