A 3 kW fuel cell generation system using the fuel cell simulator

Fuel cell system includes a fuel processor and subsystems Io manage air, water, thermal energy, and power. The overall system is high-priced and needs to peripheral devices. In this paper, the fuel cell simulator designed and manufactured as electrical characteristic of fuel cell generation system uses a simple buck converter to overcome these disadvantages. Characteristic of voltage and current (V-I) curve for fuel evil simulator is controlled by the linear function of being simplified, and we designed the fuel cell simulator. In addition, to verify fuel cell generation system performance and operation, full-bridge DC/DC converter and single-phase DC/AC inverter are designed and manufactured for fuel cell applications. The close agreement between the simulation and the experimental results confirms the validity and usefulness of the proposed fuel cell simulator.
