Abstract: PROBLEM TO BE SOLVED: To obtain a fuel cell stack enabling stable power generation by approaching the ideal static pressure distribution inside the manifold supplying the fluid to each unit cell and cooling plate, and by removing the moisture of the condensed water, etc., contained in the reaction gas for uniform gas distribution. SOLUTION: Each separator 26 provides at one side of the vertical direction on the periphery of the separator itself a gas communication manifold 27 and a gas inlet manifold 29, each of which pierces the separator to the thickness direction. On the plate surface of the separator 26, there is a gas separation ditch 28 interconnecting the separator 29 and gas inlet manifold 29. The separator 26 also provides at the other side of the vertical direction on the periphery of the separator itself a gas outlet manifold 31 which pierces the separator in the thickness direction, and there is also a gas channel 30 on the plate surface of each separator 26, connecting the gas inlet manifold 29 and the gas outlet manifold 31 with each other. Each gas commutation manifold 27 as well as each gas inlet manifold 29 and each gas outlet manifold 31, is connected in series with the other manifold of 27, as well as to those of 29 and 31 respectively. The reaction gas thus flow in the order to flow through each of the gas commutation manifolds, gas separation bitches, gas inlet manifolds, gas channels and gas outlet manifolds.

Abstract: PROBLEM TO BE SOLVED: To provide a dry desulfurization system having obviated such a problem that a conventional desulfurizing process through an oxidative reclaiming reaction of a desulfurizing agent by the aid of oxygen has caused a large quantity of heat of reaction to thereby reduce a recovery of sulfur. SOLUTION: This system is constituted as follows: a desulfurizing tower 2 for removing a sulfur constituent from a gasified gas 11 is provided with a desulfurizing agent 12 destined to be conveyed to a reclaiming tower 3 by air stream carriage; an reclaiming tower outlet gas 14 discharged from the reclaiming tower 3 is mixed with pure oxygen gas 15 and then fed to a combustor 4; a combustion exhaust gas from the combustor 4 is cooled by a cooling unit 5 and fed to a Claus reactor 6; an exhaust gas from the Claus reactor 6 is mixed with pure oxygen gas 15, passed through a selective oxidizer 7 and fed to a sulfur condenser 8; and a tail gas 17 freed from sulfur ingredient is compressed by a circulating compressor 9, fed to a heater 10 for heating to thereby turn into a reclaimed gas 13 and finally supplied into the reclaiming tower 3. Owing to the above scheme, the heat of reaction caused by the reclaiming reaction is decreased and hence the amount of circulation of the reclaimed gas is reduced, thus enabling the equipment to be miniaturized.

Abstract: PURPOSE:To pass a coolant in a coolant passage which is produced by natural convection to remove reaction heat by inclinedly arranging a fuel cell stack. CONSTITUTION:A fuel gas P is introduced into a fuel cell stack 21 through a manifold 23a, and an oxidizing agent gas Q through a manifold 23c. Electrochemical reaction is carried out in gas diffusion electrodes to generate electric energy. Gases P, Q used in electrode reaction are exhausted from manifolds 23b, 23d, and heat is generated inside the fuel cell stack 21. In this sate, a coolant C such as air flows in the direction of dotted line arrow inside cooling plates 24a-24e by natural convection. The heat generated inside the stack 21 moves from the surfaces of the cooling plates 24a-24e to the coolant C by heat transfer since the stack 21 is inclined at an angle of theta toward the floor, and the temperature rising in each unit cell is prevented.
