Abstract

The increasing demand for hydrogen as a sustainable and environmentally friendly energy source is undeniable. However, the significant cost disparity between power generation and production presents a major challenge. In response to this issue, a control strategy based on reactant stoichiometry is developed to regulate the reactant flow rate effectively. The simulation is carried out using a G-HFCS-1kW36V fuel cell with a nominal capacity of 1 kW. A hydrogen feedback-feedforward control strategy is implemented, with the minimum hydrogen stoichiometry ratio set at 1.3. The simulation results demonstrate that the feedback-feedforward control successfully improves overall efficiency as load currents are gradually increased by 2-3 A, from 5 A to 15 A. The proposed control system achieves a stack efficiency increase of 5.93% and a system efficiency improvement of 5.15%.
