And its a slam-dunk for the oxygen catalyst spillover mechanism in the above cell..  http://www.researchgate.net/profile/biswarup_satpati2/publication/258059860_facile_preparation_of_Ni%28OH%/292-MnO2_hybrid_material_and_its_application_in_the_electrocatalytic_oxidation_of_hydrazine/links/0deec5260e0e4b67b9000000    ...the effectiveness of a hybrid mix of MnO2/Ni(OH)2 as oxidation catalyst due to oxygen spillover from MnO2 onto Ni(OH)2 which is on the surface of our anode.please note:it will not work under argon or nitrogen

Thanks markscoffman. Here's more specific examples for Nickel addition to manganese oxides in alkaline sol for improved oxygen catalysis.. http://www.sciencedirect.com/science/article/pii/s0013468612020361 and also here a direct reference to nickel doping of Manganese oxides in alkali for drasticly improved oxygen catalysis http://pubs.acs.org/doi/abs/10.1021/jp0647986

Here titanium metal is cathodic vs platinum wire in alkaline sol.oxygen spillover going from TiO2 onto platinum.it can also happen in reverse direction if you use sponge platinum.

This must be documented here too.nickel hydroxide coat ontop graphite(prepared via pyrolysis of Ni(NO3)2 coat and subsequent reduction of NiO2 coat) as anode vs MnO2 as cathode in Na2CO3 sol under air.please note:this will not work under nitrogen or argon.proves beyond all doubt zero chemical combustion or corrosion going on here.I will personaly thrash any single scientist who dare claims to be the discoverer/inventor of this profitis cell.

Good news for those who want to build a nickel/MnO2/air karpen..no need to go through all the trouble of plating nickel with nickel black.a simple etch in warm pool acid will do.voltage is higher using etched as opposed to blackened nickel(to do with surface work functions)

Minute current bursts with iron vs MnO2.massive current bursts with nickel vs MnO2 ontop iron.

And nickel hydroxide ontop graphite vs MnO2 ontop steel.this overwhelming evidence for oxygen spillover effect.iron is forbidden to be cathodic vs ni(oh)2 or vs graphite.

Difference in potentials between nickel vs MnO2 coated on pt and pt wire.yet the standard potential of pt is higher than MnO2 in alkali.

MnO2 coat on platinum foil (via pyrolysis of Mn(NO3)2 coat) giving highest power densities due to zero passive layer between MnO2 and Pt metal.also due to inertness of Pt.it is closest thing to pure pyrolusite tile indicating that etched pyrolusite tile(etched with hcl) will give highest power densities by far.

Titanium is forbidden to be cathodic against nickel in alkaline sol.this will definitely not happen under argon.

Very very perplexing d3xor.he says rare-earth oxides treated with HF acid.your going to get certain lanthanum,neodymium type crystal fluorides like this.this appears to be a moray-type thing going on in hutcison's lamp but he doesn't tell us much.I wish I had a small one of those attatched to my cellfone.hutchison is a coolcat I like his artistic flair
