摘要:
An improved fuel cell makes uniform partial gas pressure of a fuel gas flowing through a gas passage formed between an electrode and a separator of a fuel cell, activating an electrode reaction in a whole region of the electrode surface along the gas passage. The inlet (105) and outlet (108) for the fuel gas are disposed on a diagonal line of the separator to define a gas passage such that fuel gas smoothly flows even though portions of the passage away from the diagonal line. This may reduce the separator size and improve the volumetric efficiency of the fuel cell and the diffusibility of fuel gas as well as the drainage of water produced by the electrode reaction.

A water electrolysis cell (100) includes an anode-side porous channel (10), a membrane electrode assembly (23), a cathode-side porous channel (30), and a separator (40) disposed on at least any one of a side of the anode-side porous channel (10) opposite to the membrane electrode assembly (23) side and a side of the cathode-side porous channel (30) opposite to the membrane electrode assembly (23) side. The anode-side porous channel (10), the membrane electrode assembly (23), and the cathode-side porous channel (30) are provided in this order. The membrane electrode assembly (23) includes an anode catalyst layer, an electrolyte membrane, and a cathode catalyst layer in order from the anode-side porous channel (10) side. An area in a plane direction of the anode-side porous channel (10) is greater than an area in the plane direction of the cathode-side porous channel (30) in a plan view.
摘要:
A fuel cell has a joint body produced by interposing an electrolyte member between a pair of electrodes, and a separator (500A) which holds the joint body. The separator (500A) comprises a rib portion (555, 556) which divides an area which forms a fluid passage for fluid which flows through the separator, wherein the plurality of regions communicate with each other. The width (W1, W2, W3) of each region is different, with the width (W1) of the regions near an inlet portion of the fluid being wider than the width (W3) of the regions near an outlet portion of the fluid.

A first process in which a fiber reinforced base is placed in a cavity of a molding die and then resin is injected into the cavity of the molding die in a state where the molding die is opened by a sum of a distance X1 and a distance at the time of completion of molding; a second process in which the molding die is closed to a state where the molding die is opened by a sum of a distance X2 and the distance at the time of completion of molding while resin in the cavity is being drained; and a third process in which the drain of the resin from the cavity is stopped and then the molding die is closed to the distance at the time of completion of molding while a die clamping pressure is maintained at a predetermined value to cure the resin, are carried out sequentially.

Disclosed are a stator and a stator manufacturing method that can manufacture a sufficiently strong stator using less time for a resin molding step and without using metal rings. Said method is used to manufacture a stator (30) in which divided core assemblies (32), wherein a coil (36) is wound around teeth (35) on divided core members (33), are arranged into a cylindrical shape. In said stator manufacturing method, divided core assemblies (32) are inserted into a fixed mold (10) in a cylindrical shape, resin sheets (37a and 37b) containing glass fibers or carbon fibers are disposed in coil-end sections (36a and 36b) of the cylindrically-arranged divided core assemblies (32), and a slide section (23) of a movable mold (20) applies pressure to and molds the resin sheets (37a and 37b), thereby turning the divided core assemblies (32) into a single unit. The slide section (23) of the movable mold (20) applies pressure to and molds the resin sheets (37a and 37b) after the divided core assemblies (32) are positioned by a cylindrical section (22) of the movable mold (20).
