Development of PEMFC stack for Fuelcell vehicle

자동차용 PEMFC 스택 개발

Hyundai motor company has designed a above 50kW-class PEMFC stack for Fuelcell vehicle based on SUV. Hyundai increased the power density of the stack through the optimized flowfield of bipolar plate, manifold structure, and improvement of sealing, etc. Also, Gas to Gas humidifier was adopted in fuelcell system to reduce the system humidification load, it had been proven by short stack test. Components of stack, bilpolar plate, manifold, were analyzed through the computer simulation, so temperature and pressure distribution in the components and system were improved. This stack tested in Bread Board which was organized similar to real vehicle system.
