| The National Hydrogen Center (CNH2), offers multidisciplinary know-how and comprehensive services ranging from basic R&D to product commercialization. Particularly, the Alkaline Electrolysis Laboratory [1], is devoted to the research and development of alkaline water electrolyzers for hydrogen production based on renewable energy sources, able to operate under variable power conditions without prejudicing performance, working life and gases produced. This facility, that was established in 2010, allows to characterize the performance of alkaline electrolysis cells, evaluate their reliability and analyze the influence of the Balance of Plant (BoP) and control strategies on the system efficiency and durability. It has as a main purpose to constitute a laboratory for alkaline electrolysis technology testing, available to the scientific community and industry. For this, it is equipped with different test benches (developed by CNH2) that work along the entire value chain from cell components and stack up to system design including peripherals. The objective of this work, framed within the activities of the Alkaline Electrolysis Laboratory, is to develop a semiempirical mathematical model that predicts the voltage and the Faraday efficiency of an electrolyzer as a function of the current. This model has been fitted with experimental data obtained with a 15 kW alkaline electrolyzer at different temperatures, pressures and electrolyte concentrations. | |
