연료전지 차량용 고출력 분리판 개발

The next generation bipolar plates for 100㎾ fuel cell stacks were developed with a concept based on the straight flow patterns to minimize the pressure drop, decrease flooding in the bipolar plate and maximize the stack power simultaneously. Cell performance tests, pressure and temperature distribution measurements were performed for various flow pattern combinations on the air, H2 and coolant sides. Results show that the stack performance and the power are increased by 12% and 400/0, respectively.
