摘要： A mixing pump device (1) used for fuel cells etc. has two inflow paths (51, 52), inflow side active valves (21, 22) arranged at the two inflow paths (51, 52), respectively, a pump chamber (11) into which liquids flow via each of two inflow paths (511, 522), four outflow paths (61, 62, 63, 64) for allowing a liquid mixed in the pump chamber (11) to flow out, and outflow side active valves (31, 32, 33, 34) arranged at the four outflow paths (61, 62, 63, 64), respectively. The inflow paths (511, 522) are opened in the directions where turbulent flow and/or swirl flow is formed in the pump chamber (11). The construction prevents a variation in the concentration of the liquid allowed to flow out of the outflow paths (61, 62, 63, 64) after the mixing in the pump chamber (11).

摘要： A cell includes an electrode plate group which is formed by laminating a positive electrode plate and a negative electrode plate with a separator interposed between them, and includes leads protruding toward directions opposite to each other from one side of the positive electrode plate and the negative electrode plate, collectors which are joined to the leads on both sides of the electrode plate group, and include connection protrusions formed so as to protrude outside, and a bag-shape battery case containing the electrode plate group joined to the collectors such that only the connection protrusions of the collectors are protruded outside. A battery module is constituted by placing a plurality of the cells in a prismatic battery case while the connection protrusions of the collectors of the cells are connected with each other, thereby making the current-carrying path between the electrode plate groups straight and short and increasing the output.
