Performance Optimizing Strategies For PEMFC And Electrode Materials

Abstract

Traditional fossil fuel-based power generation methods suffer from various drawbacks including high pollution, energy consumption, and so on. Metal bipolar plates are essential for corrosion resistance, excellent mechanical properties, high conductivity, and impermeability, and this makes them typically produced through stamping. The performance of Proton Exchange Membrane Fuel Cell electrode materials can be improved via the use of different welding methods and coating technologies. Welding techniques, such as thermo-elastic-plastic simulation, can be used to control the heat input, laser overlay welding, and protection gas-enhanced joint strength, and thus improving the welding quality and efficiency of fuel cells. Based on the implementation of ZrC coating modified Ti bipolar plates in proton exchange membrane fuel cells, the battery’s lifespan experiences an increase of approximately 1.5 times, while performance sees enhancements of over 30%. Metal carbon-based coatings and metal nitride coatings come with long-lasting protection for metal plates, accompanied by good conductivity, corrosion resistance, and strong adhesion. In the future, these technologies hold promise for applications in renewable energy and contribute to sustainable development.
