A fuel cell has: an electrolyte; an anode provided on one side of the electrolyte and having a fuel-gas consuming face at which fuel gas is consumed; a cathode provided on the other side of the electrolyte and having an oxidizing-gas consuming face at which oxidizing gas is consumed; and a fuel-gas passage portion forming a passage through which fuel gas is supplied to predetermined regions of the fuel-gas consuming face of the anode. The fuel cell has an operation mode in which almost the entire amount of the supplied fuel gas is consumed at the fuel-gas consuming face of the anode.

This separator is equipped with a first plate 33 and a second plate 32. The first plate 33 has a first hole 3341 through which reaction gas flows. The second plate 32 is to be stacked with the first plate 33, and has a second hole 3241 through which the reaction gas flows. The second hole 3241 overlaps with the first hole 3341 at the first part 3231, and is in fluid communication with the first hole 3341. The second plate 32 has a partition part 323 that divides the part 3247 of the second part which does not overlap the first hole 3341 among the second holes 3241 into a plurality of flow path parts 56. The separator 30 is further equipped with an oscillating portion 325. The oscillating portion 325 is connected to the partition part 323. The oscillating portion 325 is arranged at a position such that part of the oscillating portion 325 overlaps with the first hole 3341 of the first plate 33. The oscillating portion 325 is provided so as to be shaken by the reaction gas that flows inside the first hole 3341.
摘要:
The fuel cell system of the present invention supplies oxidant gas to a fuel cell during periods where generation of electrical power by the fuel cell is stopped. As a result, an amount of oxidant gas that is just sufficient to continue a reaction with remaining fuel gas is continued even when generation of electrical power itself is stopped. It is therefore possible to protect electrolyte membranes from damage occurring as a result of oxygen deficiency. Further, in addition to intermittent operation, the fuel cell system of the present invention is also applicable to steps for the stopping of generation of electrical power by a fuel cell in accordance with other conditions or at the time of the complete stopping of operation of the fuel cell system.

The present invention provides a method for manufacturing a woody resin molded body which comprises a step of passing a woody resin composition containing a thermoplastic resin, a cellulose powder and a blowing agent, a weight ratio of the thermoplastic resin to the cellulose powder being from 20/80 to 80/20, through a shaping die that has no core body and extruding the woody resin composition into a cooling die. A barrel temperature of an extrusion molding machine is set lower than a foaming temperature of the blowing agent, and a temperature of the shaping die is set within a foaming temperature range of the blowing agent, to thereby obtain a woody resin molded body which has a high-expanded foam layer and a low-expanded foam layer formed on the outside of the high-expanded foam layer and in which the cellulose powder is not exposed on a surface of the low-expanded foam layer. In accordance with the present invention, a woody resin molded body is provided that is lightweight and similar to natural wood in secondary processability such as nail driving and screw tightening. The woody resin molded body is free from appearance defects such as streak patterns caused by the presence of weld lines on the surface, and strength problems such as surface cracking, excels in product rigidity and strength, and can be produced with good efficiency by extrusion molding.

A request change unit outputs a command as a request under control of a judgment control unit. A response condition determination unit determines a condition that is to be matched by a correct response which is to be returned from the other device-in-communication in reply to the command if the other device-in-communication operates in conformity with a protocol. A check unit checks a response received from the other device-in-communication in reply to the command, against the condition. If the received response does not match the condition but is correctable to match the condition as a result of the check, a response correction unit corrects the received response to match the condition under control of the judgment control unit.
