Hydrogen combustion catalyst

I am interested in build a hydrogen stove for cooking and wish to use a catalytic stove. I cannot find much information about this anywhere, but only that nickel can be used for hydrogen rather than platinum.

1) Can I just use stainless scotch brite scrub pad as catalyst assuming it contains nickel? Or stainless steel wool?
2) Where can I find information about the combustion temperatures of hydrogen with various catalysts including platinum?

Here is one article with much lower temperatures than a stove:
https://pubs.acs.org/doi/10.1021/acsami.6b08019
(found with: https://www.google.com/search?&q=hydrogen+flame+catalyst)

The catalytic hydrogen combustion on Cu doped SnO2 catalysts was studied and the T50% was found to be 250 °C at a GHSV of 42310 h–1.(34) Hydrogen combustion with both reducible (TiO2) and nonreducible (ZrO2) supports has been studied with Pt and Pd substituted supports at a GHSV of 20000 h–1 and 2:1 ratio of H2:O2. T50% were obtained at 70 and 95 °C with Pd- and Pt-substituted ZrO2 catalysts, whereas Pt and Pd substituted reducible support TiO2 showed much higher activity by reducing temperatures to 37 and 35 °C.

Also pay attention to your burner configuration, the flame front moves rather quickly, generally requiring a high flow speed of the Hydrogen.

Cheers,
Tom
