Description

technical field [0001] The invention relates to a preparation method of membrane electrodes of inorganic proton exchange membrane fuel cells. Background technique [0002] Hydrogen is a ubiquitous element in nature and is a renewable and clean energy source. Scientists believe that hydrogen energy will make up for and gradually replace the increasingly depleted fossil energy sources such as coal and oil in the 21st century, and become an important part of the world's energy pattern. Proton Exchange Membrane Fuel Cell (PEMFC) is an important way to convert hydrogen energy into electrical energy. Its energy conversion efficiency is as high as 50%, and it has low operating temperature and low noise. The only discharge is pure water. , which can be widely used in vehicle power sources and stationary power station power sources. Therefore, it is generally believed that fuel cells are the preferred clean and efficient power generation technology in the 21st century (Yi Baolian, ...
