Andrew,and all,
A FUEL cel in mini can measure HYDROGEN by giving of current . Fuel cell Nickel electrodes in KOH 6,6 M heated at 80 ° C But in sensors gold is used Diafragma teflon . Grafite + Pd catalyst . Total combustion gas H2+CO sensors ,FIGARO use Pt filament at 700° C into SnO2 PELISTOR and the resistance change by combustion heat is measured.

If this was the case then I would expect the char would still be undergoing pyrolysis and the higher tar molecules splitting. As you all know town gas was originally made by heating coal to drive off CO and H2. That these molecules would survive the combustion is interesting but could simply be the dilution by other combustion products putting the air:fuel ratio out of range. How does a hydrogen cell sense the presence of hydrogen i.e. what mechanism is involved in the measuring instrument? AJH
