Research on the Thermodynamic Performance and Energy Management Strategy of Methanol Reforming Fuel Cell System

In order to reduce carbon emissions, the distributed power generation industry urgently needs to switch to high-efficiency and low-carbon fuels for power generation systems. The study examined thermodynamic performance evaluation and energy management approach of a methanol reforming fuel cell hybrid power system. According to the findings, the system uses 418.7 g/kWh of fuel and generates power with an efficiency of 40.33% under design parameters. Two approaches to energy management were developed: one based on fuzzy logic and the other on deterministic principles. The initial state of charge (SOC) of the lithium battery has a major impact on the fuel cell’s output power and fuel consumption, according to studies on energy management techniques. The cumulative fuel usage was 22.2 kg under the fuzzy control-based technique and 22.433 kg with the deterministic rule-based strategy. But under the deterministic rule-based energy management technique, the fuel cell’s output variation is comparatively less frequent, which makes it more appropriate for real-world application settings.
