Description
technical field [0001] The invention belongs to the research field of alkaline water electrolyzers, and more specifically relates to a method and system for analyzing the working characteristics of alkaline water electrolyzers based on finite element elements. Background technique [0002] As the world's environmental pollution is becoming more and more serious and the energy crisis is intensifying, the construction of ecological civilization and sustainable development have become the goals that all countries are competing to pursue. Renewable energy represented by wind power will surely become the main power generation energy in the future. In order to reduce wind curtailment and promote wind power consumption, a lot of work has been carried out in the regulation of using abandoned wind power to produce hydrogen and store energy. At present, when studying the wind power hydrogen production system, researchers mostly use mathematical expressions to represent the alkaline w...
