An ion exchange resin memberthat serves as an impurity remover for removing impurities from fluid F discharged from a fuel cellis placed in a discharge passage for the fluid F to flow through, and a dispersion means for dispersing the fluid F over, and making the fluid F flow to, an entry-side surfaceof the ion exchange resin memberis placed upstream from the ion exchange resin member. Also, a gas discharge part and a liquid discharge part are placed downstream from a fluid outlet of the ion exchange resin member, and a liquid-movement-preventing means for preventing a liquid in the fluid discharged from the fluid outlet from moving toward the gas discharge part is placed between the ion exchange resin memberand at least either the gas discharge part or the liquid discharge part.

Fuel cell system

A fuel cell system () capable of securely removing moisture in particulate form floating in an exhaust gas passage along with impurities mixed in the moisture, enhancing the performance of a fuel cell, and extending the service life of the fuel cell. The fuel cell system () includes a gas circulation system for recirculating and resupplying an exhaust gas to a fuel cell (). This gas circulation system is equipped with an ion exchange resin member () that adsorbs impurity components contained in the moisture particles mixed in the exhaust gas flowing through the gas circulation system. The gas circulation system resupplies fluid that has passed through the ion exchange resin member () to the fuel cell ().

In a method of manufacturing a sliding member, a granular spraying material is sprayed on at least a part of a surface of a body portion made of a structural material in at least partially fusing condition and in the direction which is parallel to or diagonal to a sliding surface. Then, a sprayed layer is formed by depositing the spraying material in the direction which is perpendicular to the sliding surface. The sliding surface is a section of the deposited spraying material which is obtained by grinding or cutting the sprayed layer in depositional direction. A piston comprises a piston body having a broad groove which is broader than a ring groove, a sprayed layer comprising a lower sprayed layer which is formed by spraying the spraying material in the direction which is diagonal to an outer periphery of the broad groove and which contains higher ratio of spraying particles having low fusion temperature, and an upper sprayed layer which is formed by spraying the spraying material in the direction which is perpendicular to the outer periphery of the broad groove and which contains higher ratio of spraying particles having high fusion temperature, and a ring groove which is formed by grinding or cutting the upper sprayed layer in depositional direction. Therefore, excellent wear resistance and the like can be obtained.

A cylinder head for an internal combustion engine includes a metallic cylinder head body, and a valve seat. The cylinder head body is provided with an inlet port, and an outlet port which are opened and closed by an inlet valve, and an outlet valve, respectively. The valve seat is disposed at an end of the inlet port or the outlet port, has a contact surface which is contacted with and separated from the inlet valve or the outlet valve, and is formed of a laminated substance. The laminated substance is formed as flakes by thermal spraying particles in a predetermined depositing direction, and the contact surface is inclined by an angle of from 0 to 60 degrees with respect to the depositing direction. In the cylinder head, the valve seat is strongly bonded to the cylinder head body, exhibits improved frictional characteristics on the contact surface, and has such high thermal conductivity in a depth-wise direction that it can be readily cooled to a low temperature.
