In this study, Ni–Fe–Co spinel electrocatalysts, with a specific nanorod morphology engineered to optimize ion diffusion, were synthesized via a sono-hydrothermal method and evaluated as anodes in AEMWEs. Four different compositions of nanostructured Ni–Fe–Co oxides, all based on the NiCo<sub>2</sub>O<sub>4</sub> spinel, and named NiCo3–S, NiCo4–S, NiFe1–S (10 % Fe), and NiFe2–S (20 % Fe) were synthesized and spray-coated onto nickel felt gas diffusion layers.

The structural analysis confirmed well-defined spinel phases and a nanorod morphology for all the electrocatalysts, with NiFe2–S exhibiting enhanced crystallinity and smaller nanorod dimensions. Electrochemical tests revealed that AEM cells equipped with NiFe2–S anodes achieved a low cell voltage of 1.808 V at 1 A. cm<sup>−2</sup> and 2.06 V at 2 A. cm<sup>−2</sup>, outperforming other electrocatalysts. A 45-h DC stability test showed only a slight voltage increase (1.815 V–1.866 V), while a 20-h accelerated stress test (AST) confirmed minimal degradation.

In the simulations, both the initial hydrogen pressure and the radius of the hole through which hydrogen is released are varied. As a result, critical pressure values required for successful ignition of various compositions during hydrogen release through holes of different radii are determined. It is shown that the hydrogen release into a stoichiometric hydrogen-air mixture could lead to the combustion wave propagation in a detonation mode following the ignition. On the one hand, this is important for assessing the risks of hydrogen explosion hazards, and, on the other hand, can become the basis for new technological solutions for stable ignition in combustors without the use of additional devices, such as a spark ignition system. Thus, the work demonstrates that a relatively small mass of hydrogen is required to ignite a stoichiometric hydrogen-air mixture.
