Abstract
Official abstract text for this publication.
A fuel cell includes: a membrane-electrode-gas diffusion layer assembly; a separator positioned in one side with respect to the membrane-electrode-gas diffusion layer assembly; a frame member supporting the membrane-electrode-gas diffusion layer assembly and joined to the separator, wherein the frame member includes: a base layer; an adhesive layer having thermoplasticity, having a linear expansion coefficient greater than that of the base layer, and joining the base layer and the separator; and a coating, layer provided on a side, opposite to the adhesive layer, of the base layer, having a liner expansion coefficient greater than that of the base layer, and not containing an adhesive component.
First claim
Opening claim text (preview).
What is claimed is: 1 . A fuel cell comprising: a membrane-electrode-gas diffusion layer assembly; a separator positioned in one side with respect to the membrane-electrode-gas diffusion layer assembly; a frame member supporting the membrane-electrode-gas diffusion layer assembly and joined to the separator, wherein the frame member includes: a base layer; an adhesive layer having thermoplasticity, having a linear expansion coefficient greater than that of the base layer, and joining the base layer and the separator; and a coating layer provided on a side, opposite to the adhesive layer, of the base layer, having a liner expansion coefficient greater than that of the base layer, and not containing an adhesive component. 2 . The fuel cell of claim 1 , wherein the coating layer has a liner expansion coefficient smaller than that of the adhesive layer, and the coating layer is thicker than the adhesive layer. 3 . The fuel cell of claim 1 , wherein the coating layer has a liner expansion coefficient greater than that of the adhesive layer, and the coating layer is thinner than the adhesive layer. 4 . The fuel cell of claim 1 , wherein a gasket is provided on the coating layer. 5 . The fuel cell of claim 1 , further comprising another separator joined to the separator. 6 . The fuel cell of claim 1 , wherein the adhesive layer is modified polyolefin including at least one polyolefin including a functional group. 7 . The fuel cell of claim 6 , wherein the modified polyolefin includes: any one of or combination of acid anhydride including maleic anhydride; carboxylic acid including acrylic acid and methacrylic acid; alcohols including vinyl alcohol and ethylhexyl acrylate; silane coupling agent; epoxy resin; and urethane resin.
