Modeling and simulation for 1.2 kW PEM fuel cell power generation of isolated load conditions

摘要

The PEM Fuel cell are deliberated as one of the almost favourable devices for isolated/grid connected distributed generations (DGs) due to its cleanliness, modularity and higher potential capability. This paper presents the modeling and simulation for 1.2 kW PEM Fuel Cell Power Generation of Isolated Load conditions. The proposed scheme consists of a Fuel rate selector, Fuel rate regulator, Fuel cell stack, Boost converter, Filter circuit and Load. The PEM Fuel cell model includes the dynamics of reactant flow, membrane resistance, stack efficiency and capacitance as well as steady-state equation. Modeling and simulation of the PEM fuel cell power generation are carried out by Matlab software. The variation of load corresponds to the output voltage, current, and fuel cell flows rates are examined. The present modeling and simulation results are validated with sample experiments results are conducted in VSB-Technical University of Ostrava.
