| Abstract |
In order to compensate a loss from the dynamic, a hydrogen fuel cell supplies the hydrogen more than 10% to its rated capacity. It brings the issue that a utilization rate of fuel cell degrades to 10%, therefore, the method is applied which recirculating the emitted hydrogen after their reaction. When their hydrogen recirculating, it results in emitting not the pure hydrogen but impurity, as a result it enables the electric energy to unstable. When a load requires certain power, a membrane of fuel cell has damaged due to voltage drop. In order to develop the charger which charging the energy into battery in fuel cell and battery hybrid system, it requires protection operation according to fuel cell output characteristic results from hydrogen recirculation. In fuel cell charger, selecting the level of protection operation voltage and current through experiment brings significant problem that damage of costly fuel cell. In this paper, we explain the design and control method of the fuel cell simulator which has output characteristic according to current density, temperature of fuel cell including hydrogen recirculation function and verify the validity through simulation and experiment. |
