Abstract: A fuel cell includes: a membrane electrode assembly of a flat plate shape including an electrolyte membrane and an electrode catalyst layer, the membrane electrode assembly having a first side intersecting a flow pathway of a reactive gas on a surface of the fuel cell and a second side differing from the first side; a frame member of a flat plate shape including an opening part for arrangement of the membrane electrode assembly, the opening part having a first frame side corresponding to the first side and a second frame side corresponding to the second side; and an adhesive member for bonding between an outer periphery of the membrane electrode assembly and an inner periphery of the frame member. The thickness of the adhesive member in an area from an inner peripheral edge at the second frame side toward a center of the frame member may be greater than the thickness of the adhesive member in an area from an inner peripheral edge at the first frame side toward the center of the frame member.

Abstract: An apparatus for controlling an internal combustion engine having an exhaust purifying catalytic device which absorbs nitrogen oxides contained in exhaust when the engine is in a lean-combustion mode and which deoxidizes the absorbed nitrogen oxides when the engine is in a rich-combustion mode. The engine control apparatus includes an electronic control unit for estimating the amount of purifying capability reducing substances other than nitrogen oxides, which decreases the nitrogen oxide adsorbing ability of the catalytic device, absorbed by the catalytic device, on the basis of the accumulated value of vehicle travel distance, fuel consumption of engine, or intake air amount. The control unit changes the operating condition of engine so that the exhaust gas temperature is increased when it is judged that the estimated adsorption amount has reached a predetermined adsorption amount.
