  • Patent number: 10205182
    Abstract: Oxidant gas flows to the fuel cell stack through an oxidant gas supply channel. Oxidant off-gas is discharged from the fuel cell stack through an oxidant off-gas exhaust channel. A refrigerant is discharged from the fuel cell stack through a refrigerant exhaust channel. An outlet sealing valve is provided in the oxidant off-gas exhaust channel. The outlet sealing valve includes a main body, a valve seat, a valve body, and a refrigerant passage. The main body has a passage through which the oxidant off-gas flows. The valve seat is provided in the passage. The valve body is provided in the passage to be seated on the valve seat to close the passage. The refrigerant passage is branched off from the refrigerant exhaust channel. The refrigerant flows in a vicinity of at least one of the valve seat and the valve body through the refrigerant passage.

  • Patent number: 9978490
    Abstract: A low-loss compact and a method for producing the compact are provided. A method for producing a compact by using coated soft magnetic powder that includes coated soft magnetic particles constituted by soft magnetic particles and insulating coatings coating outer peripheries of the soft magnetic particles includes a raw material preparation step and an irradiation step. In the raw material preparation step, a raw compact is prepared by press-forming coated soft magnetic powder. In the irradiation step, part of a surface of the raw compact is irradiated with a laser. Irradiating a part of a surface of a raw compact with laser increases the number of disrupted portions of conductive portions where constituent materials of the soft magnetic particles at the surface of the raw compact have become conductive to each other, and the loss of the compact can be decreased.
