Discussion

Innovative electrocatalysts achieve high performance in hydrogen oxidation for alkaline fuel cells, indicating enhanced stability.

The optimized electrocatalyst exhibits 92.3% retention in CO tolerance during 5000 seconds of testing.
With a peak power density of 1.76 W cm−2, it shows remarkable efficiency under H2/O2 conditions in AEMFCs.
Studies reveal enhanced adsorption properties due to the Ni anchored Ru/RuO2 heterostructure, optimizing *H and *OH binding.
Long-term stability is confirmed with negligible decay after 100 hours at 0.5 A cm−2 in the fuel cells.

Liu et al. (2025) studied this question.
