Problems solved by technology

However, the actual flow of reactant gases in the channel remains laminar, so it is difficult to remove small water droplets from the open pores of the GDL

Abstract

The present invention provides a fuel cell separator, in which a vortex generating structure is formed on the surface of a channel of the separator to induce a vortex of fluid (i.e., hydrogen and air) flowing through the channel, thus facilitating the supply of reactant gases and the removal of water droplets from a gas diffusion layer (GDL).

Description

technical field [0001] The present invention relates to fuel cell separators. More particularly, it relates to a fuel cell separator in which a vortex-generating structure is formed on the channel surface of the separator to induce vortex flow in fluids (i.e., hydrogen and air) flowing through the channels, thereby facilitating supply of reactant gases and diffusion from the gas layer (GDL) to remove water droplets. Background technique [0002] The research and development of hydrogen fuel cell vehicles as an environmentally friendly vehicle continues to progress. The fuel cell system applied to hydrogen fuel cell vehicles includes a fuel cell stack that generates current through an electrochemical reaction between reactive gases, and supplies the fuel cell stack as fuel. The hydrogen fuel processing system (FPS), the air processing system (APS) that provides oxygen (including air) as an oxidant for the electrochemical reaction in the fuel cell stack, and removes the react...
