Design and applications of megawatt-scale PEMFC system
Proton exchange membrane fuel cells(PEMFC)can realize the combined supply of electricity and heat,which is an important technical path to support the zero-carbon energy strategy.The megawatt-scale PEMFC system is introduced and analyzed,the selection basis and suggestions for inverters,transformers,plate heat exchangers,energy management systems and other components in the engineering application are provided,and it is pointed out that the components with the highest proportion of self-consumption in system operation are air compressors and cooling fans,accounting for 82.0%and 10.7%of the total self-consumed power,respectively.The commercial application of megawatt-scale PEMFC system in a chlor-alkali plant can generate electricity from the originally empty hydrogen,improve the energy utilization efficiency of the plant,and create economic benefits.
