It has to be above 125 F, it has to be between around .7% and 5% mixture in air, and it needs a fairly robust ignition source.
Compare that to pure hydrogen, it's hard to keep that stuff from burning.

Tell me about it. I had to design purge systems for coal gasification fuel systems for gas turbines in the 1990s. You can't purge with air, until after you've purged with something else! They used either CO2 or Nitrogen. My solution was to use methane.
The flammability limit on methane is 20 to 1 (air to methane) on the low end to about 4-5 to 1 on the high end.
Hydrogen is 20 to 1 on the low end and 1 to 20 on the high end! It burns in almost any condition. Very dangerous to attempt to use as a motor fuel!
