Electrostatic filtering for filter system of fuel cell

In current fuel cell system, since some ultra-particles such as carbon and so on are filtered by fine filter, and collected on the filter surface in long term, they cause high pressure, and give damages to the filter system. This paper proposes to add electrostatic filtering as another process in front of fine filtering in order to remove these ultra-particles. In this process, a drum is partly charged in order to capture ultra-particles, the drum then turns and take the captured ultra-particles to another part. Finally, the drum is partly discharged in order to drop the ultra-particles, and the air input to the fuel cell system is cleaned up. The simulations are performed to evaluate the performance of the proposed system, and the results show that the efficiency of the system is approximately enhanced 90%.
