A Simulation Study of Residential Fuel Cell Cogeneration System Based on Load Energy

Residential fuel cell cogeneration systems have gained much interest due to its high efficiency. In the present study, we have performed numerical simulation of residential fuel cell cogeneration system which includes a fuel cell/battery hybrid system. The cogeneration system consists of 1kW PEFC, two 60Ah batteries, inverter/converter and reformer. Several empirical models have been employed for respective components to improve the accuracy of the simulations. The load varies seasonally. The present simulations can successfully predict the characteristics of the hybrid cogeneration system and thus it can be utilized for establishing an optimal operating strategy of the system.
