Abstract

The present invention relates to a porous plate for a fuel cell, a porous body for a fuel cell manufactured by using same, a stack for a hydrogen fuel cell having improved durability by using same, and a hydrogen fuel cell, wherein in manufacturing a porous body for a fuel cell constituting a stack of a hydrogen fuel cell, degradation of cell efficiency and durability due to abrasion caused by sharp edges or friction etching can be prevented. In particular, when manufacturing as a porous body, by forming an edge-preventing groove in advance in a portion where a sharp edge occurs, a portion in contact with a gas diffusion layer (GDL) can be formed smoothly after the porous body is manufactured, and thus, through this, a problem, such as wear or friction etching, due to contact between the porous body and the gas diffusion layer (GDL), can be minimized, and the efficiency and lifetime of a hydrogen fuel cell can be greatly improved.

Abstract

The purpose of a nonlinear porous body for a fuel cell of the present invention is to improve electrical energy production efficiency. To this end, the nonlinear porous body for a fuel cell of the present invention comprises: a base portion in which a vertical cross-section is formed so as to be bent along a longitudinal direction in which a fluid flows; and a fluid penetrating portion which penetrates the base portion and has a non-linear pattern along the longitudinal direction of the base portion such that the movement path of the fluid becomes non-linear. Accordingly, when the nonlinear porous body for a fuel cell of the present invention is applied to a fuel cell, the reaction area between a gas and a gas diffusion layer is maximized and thus the output of cells is increased, and thereby, the performance of the entire fuel cell is improved and more electrical energy per unit size can be produced. Therefore, it is possible to make a hydrogen vehicle compact while reducing manufacturing costs thereof.
