Description

technical field [0001] The invention relates to the field of energy conversion devices, in particular to a preparation method and device for a novel two-dimensional patterned electrode. Background technique [0002] With the rapid growth of world energy consumption and the limitations and shortcomings of traditional fossil energy, the direction of new energy is a focus of the future development of human society, and hydrogen energy has begun to attract the support and support of many governments with its unique advantages. Hydrogen energy has the advantages of high energy density, environmental protection and pollution-free use. At the same time, the efficiency of directly and efficiently converting hydrogen into electrical energy through a proton exchange membrane fuel cell (PEMFC) is much higher than that of many internal combustion engines. However, there is not a large amount of available hydrogen molecules naturally on the earth, and hydrogen must be produced through ar...
