Hello Jay, platinum in general as is palladium are mostly inert metals that "catalyze" a reaction - make it happen below the initial reaction temperature.

Hydrogen and Oxygen can coexist together happily as ""hydrogen-knallgas" up to around 570C temperature where there is an instant hydrogen oxidation releasing thermel energy and water.generating 241.8 kJ of energy for every mole of H2 that is oxidized.

The problem with the so called "hydrogen" explosion is similar to the oxidation of NG or gasoline etc., when there is a spark of very low energy which spark inside temperature is above the 570C see en.wikipedia.org

Some more on this subject is at sciencedirect.com as an example.

To avoid those instant oxidations of hydrogen the easies catalyst for H2 O2 recombination, was platinum but now various nickel alloys or mesh of Ni & Pt do the same as are certain types of iron rust and Nano-carbon structures

A lot of research is invested on this subject and almost every week there is a new combination that enables controlled oxidation of hydrogen by take-in out the energy as electricity - (sucking the oxidation energy).

To give you a better real world feeling imagine that you burn in a stove some wood but instead of the stove warning the room you convert its thermal energy to electricity - hope you got the idea.

Those are basic laws of physics that energy only transforms itself into various forms but never disappears. What you do not recuperate as the wanted energy is called reaction inefficiencies. Therefore at 60% efficiency in fuel calls 60% is converted to electricity and - the remaining 40% of the energy is "lost" to thermal energy - actually in my project I use it for warming water and cooling the fuel cell with water.
