Sorry Alfred, I did not mean to infer that because hydrogen is the smallest molecule that it will allways make problems with leaks on equipments .
I have worked on and of with Hydrogen since 1968, first with Lugi/H&G water gas units, then Namptha methane reformers, and also the united technologies reformer . and solar Vasserstoff unit to date I have experienced no serious problems .
My point essentially was that all kit has weak points with compressors and turbines it is seals and bearings, With sfety valves it is the seat is never again perfect tight after having lifted, and with fuel cells it looks to be membrane/seal
