As long as you keep the hydrogen concentrations above 95% or below 2% (IIRC) hydrogen won't ignite. It's used in electrical generators (think ConEd, city-sized generators) under positive pressure to dissipate heat from the internals because hydrogen is more thermally conductive than air. Crazy, right?
Using it to loose weight on a robot is just silly.
