Cell voltage monitoring All-in-One. A new low cost solution to perform degradation analysis on air-cooled polymer electrolyte fuel cells

“…In the same way, the implementation based on individual cells voltage monitoring versus operating current allows detecting and quantifying at the same time the degradation accumulated by each cell in the different zones of the polarisation curve [16,51]. Therefore, the degradation study based on the polarisation curve is the most widespread solution [9,49,52], and the use of cell voltage monitoring (CVM) systems as the physical tool to carry it out.…”
