At present, the development of the domestic hydrogen energy industry is in the initial exploration stage of cost reduction, efficiency improvement, technological innovation, and collaborative promotion. The synergistic effect of upstream and downstream collaboration in the hydrogen energy industry chain has not yet been fully demonstrated. We need to focus on major industrial issues and jointly promote the healthy development of China's hydrogen energy industry. On October 12, 2023, the China Electric Hydrogen Coupling and Hydrogen Chemical Technology Innovation Conference was held at the Zhongcheng Temple of Heaven Holiday Hotel in Beijing.
Aerospace Hydrogen Energy proposed at the forum that the main way to reduce the cost of PEM electrolytic cells is to improve electrode activity, and the working current density of the battery stack is increased from about 1.0A/cm2 to over 2.5A/cm2 at the current level; Improve the slurry ratio and coating process, reduce the loading of platinum and iridium catalysts, control and improve product consistency, improve battery assembly level, and extend the service life of the electrolytic cell.
