Abstract
Official abstract text for this publication.
A method of welding comprising contacting a first electrode to a porous body flow path, contacting a second electrode to a plate material, pressing the porous body flow path and the plate material by the first and second electrodes in a thickness direction of the plate material, and spot welding the porous body flow path and the plate material, wherein: a deformation of the plate material in a direction of the second electrode pressing the plate material is smaller than a deformation of the porous body flow path in a direction of the first electrode pressing the porous body flow path.
First claim
Opening claim text (preview).
What is claimed is: 1 . A method of welding comprising contacting a first electrode to a porous body flow path, contacting a second electrode to a plate material, pressing the porous body flow path and the plate material by the first and second electrodes in a thickness direction of the plate material, and spot welding the porous body flow path and the plate material, wherein; a deformation of the plate material in a direction of the second electrode pressing the plate material is smaller than a deformation of the porous body flow path in a direction of the first electrode pressing the porous body flow path. 2 . The method of welding in accordance with claim 1 , wherein an area of an end face of the first electrode is smaller than an area of an end face of the second electrode. 3 . The method of welding in accordance with claim 1 , wherein the porous body flow path is joined by the spot welding at a part thereof that surface-contacts the plate material in a state before the spot welding is performed. 4 . The method of welding in accordance with claim 1 , wherein the spot welding is initiated after the first electrode surface-contacts the porous body flow path. 5 . The method of welding in accordance with claim 1 , wherein the plate material is a shield plate that shields a seal material when the plate material is assembled as a fuel cell.
