Fuel cell stack and fuel cell system including the same

摘要

A fuel cell stack and a fuel cell system, the fuel cell stack including a plurality of membrane electrode assemblies, the membrane electrode assemblies being configured to generate electrical energy by an electrochemical reaction of a fuel and an oxidizer; and a plurality of bipolar plates positioned adjacent to the membrane electrode assemblies and between the membrane electrode assemblies, the bipolar plates including a fuel channel at one side thereof and an oxidizer channel at a second, opposite side thereof, wherein the bipolar plates include a plurality of cooling channels penetrating therethrough, the cooling channels having a curvature along a length thereof.
