  • Publication number: 20160072135
    Abstract: A manufacturing method for manufacturing a fuel cell separator assembly includes a joining step for bringing opposing projections of uneven portions of separators into contact with each other through use of pressing members to join the projections through use of a welding robot. In the joining step, an elastic member is interposed between the pressing members and at least one of first and second separators so that a pressing force from the pressing members is imparted to the first and second separators.

  • Publication number: 20160052407
    Abstract: A plurality of projections is arranged in a matrix on the upper surface of the housing of a contactless charging unit (110). When supplying power wirelessly to an onboard power reception device, a beam emission unit in a beam reception and emission unit (120) emits a laser beam progressing along the upper surface of a power transmission unit (170) to scan the upper part of the entire upper surface of the power transmission unit (170). When receiving a reflected beam, the beam reception unit in the beam reception and emission unit (120) sends the results of beam reception to a determination unit. The determination unit determines the presence or absence of a foreign substance supported on at least one projection existing on the upper surface of the contactless charging unit (110) on the basis of the results of beam reception.
