Abstract: Assembled battery (80) includes two battery cells (20A, 20B) arranged in parallel, which are accommodated in single parallel-arranged module (50). Inter-battery airflow passage (65) is formed between parallel-arranged modules so as to allow cooling air to pass therethrough. Pressure contact members (60) each have hollow portion (61) formed by solid portion (66) and thin wall portion (61a) and are arranged in layers. Hollow portion (61) forms a cooling air passage. Cooling air supplied to the cooling air passage is sent to battery cell (20B) on the rear side, and directed and supplied toward the central part of battery cell (20B). Solid portions (66) in area A hold electrode tab (25) therebetween while pressure contact members (60) are in contact with each other in area B.

Abstract: A film-covered electrical device packaging system of the present invention includes frame member (10) which holds film covered battery (1) by an outer periphery portion of film covered battery (1) and which has a portion thicker than the thickness of power generation element (2), and in which waste gas channel (10i) is formed in a position corresponding to gas discharger (8), and first pressure plate (20) which sandwiches frame member (10), in which penetrating portion (22) is formed in a position corresponding to waste gas channel (10i), and in which gas guide groove (21) communicating from through holes (22) to sidewall face (24) is formed.

Abstract: A stopper valve for a fuel tank is provided which includes a valve housing, float movable upward/downward within the housing, valve element disposed on the top of the float, space formed downstream of the valve element and open via a through hole, and air inlet/outlet port provided downstream of the space and leading to a canister. One end portion of the air inlet/outlet port is located within the space and an opening is formed in the same end portion so as to be eccentric to the through hole and face upward.
