SEPARATOR AND FUEL CELL STACK USING THEREOF

摘要

PURPOSE: A separator and a fuel cell stack using thereof are provided to improve the flow speed of reactive gas with the low pressure, and to stably generate the electrical energy without degrading the power generation capacity. CONSTITUTION: A fuel cell stack(100) comprises the following: an electricity generation unit(30) including a membrane-electrode assembly(31), and separators(32,33) closely located on both sides of the membrane-electrode assembly; and a reactive gas flow path formed on the separators. The reactive gas flow path includes a first directional path, and a second directional path connected to the first directional path.
