摘要:
In a heat exchange reformer unit, a reforming passage supporting reform catalyst for inducing reforming reactions and a combustion passage supporting oxidizing catalyst for combustion are disposed adjacent to each other with a plate portion interposed therebetween. Heat-exchanging passages of the reforming passage that produce reformate gas that contains hydrogen from supplied reformation material, and heat-exchanging passages of the combustion passage that supply heat, which is generated by catalytically burning supplied fuel, to the reforming passage constitute a parallel-flow heat exchanger. Reformation material guide passages for introducing reformation material into the heat-exchanging passages in a predetermined direction, and mixed gas guide passages for introducing fuel into the heat-exchanging passages in a direction intersecting the gas flow direction in the reformation material guide passages, are provided upstream of the heat-exchanging passages in a gas flow direction.

A heat exchanger includes: a stacked core formed by stacking a plurality of unit plate members in each of which passage formation portions are formed independently of each other to extend from a heat-exchange passage formation portion along a plane; a case formed in accordance with the outer shape of the stacked core, and which houses the stacked core such that heat-exchange media flow into and flow out of the stacked core; and a join portion that serves as a sealing mechanism that supports the stacked core such that the stacked core does not contact the case, and that forms a heat-insulation layer between the case and the stacked core, wherein the heat-insulation layer is a closed space separated from the outside.

摘要:
A method for brazing a first metal member, on which an oxide forms during brazing, and a second metal member, in which a high-wettability metal having a wettability with a brazing filler metal that is higher than that of the oxide is applied to at least a brazing surface of the first metal member. The first metal member and the second metal member are then joined by heating the brazing filler metal to melt the brazing filler metal. The oxide covering film is formed on the portion of the surface of the first metal member to which the high-wettability metal was not applied.

The fuel cell system 1 has a reformer 2 and a fuel cell 3. The reformer 2 has a reforming reaction channel 21 that generates a hydrogen-containing reformed gas Ga and a heat exchange channel 22 for heating. The fuel cell 3 has an anode channel 32 to which the hydrogen-containing reformed gas Ga is supplied, a cathode channel 33 to which an oxygen-containing gas Gc is supplied, and an electrolyte 31 formed between them. The electrolyte 31 is a laminate of a hydrogen-separating metal layer 311 and a proton conductor layer 312. The fuel cell system 1 has a cathode offgas line 46 for feeding the cathode offgas Oc discharged from the cathode channel 33 to the reforming reaction channel 21.

A power conversion circuit system comprises a primary conversion circuit, a secondary conversion circuit, and a control circuit for controlling the primary and secondary conversion circuits. The primary conversion circuit comprises a primary full bridge circuit, which includes a bridge section composed of both a primary coil in a transformer and a primary magnetic coupling reactor in which two reactors are magnetically coupled, a first input/output port disposed between a positive bus bar and a negative bus bar of the primary full bridge circuit, and a second input/output port disposed between the negative bus bar of the primary full bridge circuit and a center tap of the primary coil in the transformer. The secondary conversion circuit has a configuration similar to that of the primary conversion circuit.
