摘要

A semiempirical 1D mathematical model of current–voltage performance of proton exchange membrane (PEM) fuel cell has been developed. The main parameters of the model are flow rates and pressures of hydrogen and air in the fuel cell, temperatures and dew points of hydrogen and air, and the geometric parameters of the membrane–electrode assembly (MEA). The largest relative discrepancy between the calculated and experimental electrical powers generated by the PEMFC does not exceed 7.4%. The calculation algorithm, implemented without the use of significant computing resources and software packages, can be used in various applications of PEM fuel cells (PEMEC), including the creation of emulators and digital twins, which will increase their level of reliability and safety.
