FUEL CELL SEPARATOR AND FUEL CELL STACK WITH THE SAME

摘要

A fuel cell separator is provided to prevent a flooding phenomenon by smoothly discharging water accumulated within a reactive gas channel to the outside without a purging method. A fuel cell separator(130), which is an element of a unit cell for a fuel cell stack and contacted to a membrane-electrode assembly, comprises the following units. A reactive gas channel is formed on a side of the fuel cell separator to face the membrane-electrode assembly so that the reactive gas can flow for an electrochemical reaction. Cooling channels(170,180,190) are arranged in the back side of the fuel cell separator so that coolants can flow.
