Of the Al cell or the MnO2 cell d3x0r
the aluminum... was trying to do some searching on it. 


MnO2 is not something I'll be able to try; lack of incentive to purchase... the other I have the peices laying around

2Al + 3H2O = Al2O3 + 3 H2...and also 2Al + 6O(from air) = 2Al2O3...Al2O3 then dissolves slightly in bicarbonates to form aluminates.not enough incentive to get hold of pyrolusite? You don't want to be the first to violate kelvins law on youtube? It gives more of a kick than karpens original.

The MnO2 cell gives about 3-4 times more power than karpens gold/plat cell.

Change my search terms from calcion-carbonate reaction to just 'aluminum carbon battery' and found immediately instructable videos using various things... even a Aluminum air battery - http://sciencegeekgirl.com/documents/TPT_Salty_Science.pdf ... that just uses the O2 from air...
Although using graphene ink on Al foil would make a nice compact stack ... hundred squares could get 50V battery :)  only... 50uA... still need 400 of those to get what I need for amps :)


Hmm... http://en.wikipedia.org/wiki/Manganese_dioxide - first paragraph....
Manganese(IV) oxide is the inorganic compound with the formula MnO2. This blackish or brown solid occurs naturally as the mineral pyrolusite, which is the main ore of manganese and a component of manganese nodules. The principal use for MnO2 is for dry-cell batteries, such as the alkaline battery and the zinc-carbon battery.[2] MnO2 is also used as a pigment and as a precursor to other manganese compounds, such as KMnO4. It is used as a reagent in organic synthesis, for example, for the oxidation of allylic alcohols.

that's not a thermal cell either :p

You forgot to google the words: 'fuel cell O2 catalyst MnO2' d3xor (-: Its a inverted-thermal cell.no need for a temperature gradient.

Reactions for the cell in NaOH electrolyte: anode(nickel,totaly inert) 2OH-> O + H2O + 2e- and at the MnO2catalyst cathode: O + H2O + 2e- > 2OH-

Voltage for this cell calculated same as for karpens original: E= RT/nF ln kb1/kf1 - RT/nF ln kb2/kf2. K is rate constant of forward/backward reactions for O + H2O + 2e- >< 2OH-

I like the idea; it has been a long time since chemistry, but I remember liking it for it's algebraic simplicity :)


Nickel... "nickel catalyst hydrogenation"  started as 'nickel catalysis of hydroxide' but turned out 'nickel-hydroxide' is used as a catalyst.
Hydrogenation: http://en.wikipedia.org/wiki/Hydrogenation 


Still need to do more digging

Your getting closer d3xor.did you know that nickel is so inert in alkali solution that its sometimes used as an oxygen catalyst in fuel cells? It coats with impenetrable Ni(OH)2 layer. You must dip your pyrolusite in HCl and warm for a few minutes to pit it with massive surface area.you must electroplate your nickel with nickel-black for area there.I get roughly 50-100micro-amp per mm2 pyrolusite!!! What's a square cm going to do..I can only get hold of tiny samples here.if you can get hold of large tantalum capacitors you can crack the shell off and get a nice size block of solid pyrolusite.

Large tantalum caps are used in the power circuit for computer hard-drives.usually yellow blocks stuck on circuit board in groups,each one about the size of half a pinkie-nail

Just because you can write a chemical equation doesn't make it so, however :)


http://www.technologyreview.com/news/411382/platinum-free-fuel-cell/  ( a good summary fuel cells, and why they prefer an acidic environment vs a basic one)
"The nickel catalysts used in previously developed alkaline fuel cells weren’t very efficient because they quickly got oxidized, so alkaline fuel cells have used the same platinum catalysts as their acidic counterparts. The Wuhan researchers created an anode coated with nickel nanoparticles decorated with chromium that’s more tolerant to oxidation than previous nickel catalysts." [/size]

[/size]
so apparently the O generated at the nickel anode likes to stick to the nickel instead of remaining free[/size]

Google shopping for 'pyrolusite crystal'
can get pretty big chunks... don't add "-ebay" though cause that fails :)

Several listings come back as "PYROLUSITE crystals in a geode"
Geodes are remnant ancient tech, you know? :)   They really can't possibly occur naturally.  (just my theory)

------
Black Nickel - http://en.wikipedia.org/wiki/Nickel_electroplating#Black_nickel "Black nickel plating is a typically plated on brass, bronze, or steel in order to produce a non-reflective surface.[7] This type of plating is used for decorative purposes and does not offer much protection" ? Nickel ammonium sulfate NiSO4·(NH4)2SO4·6H2O  ?  what's that leave behind? some sort of NiO? 

(plastic black nickel plated...)
http://www.ebay.com/itm/Bell-Stopper-With-Lid-Cord-Ends-Lock-Stopper-Plastic-Black-Nickel-Plated-Toggle-/350963657334?pt=LH_DefaultDomain_0&var=620216186668&hash=item51b7106a76

Does the nickel actually have to be a core of nickel if it's electroplated there's no actual nickel surface?

Fuel cells are either alkaline or acidic.MnO2 is used in alkaline fuel cell catalysts because it is totaly inert in alkali.try it d3xor,its up to you.one thing I assure you,it will last forever and a day (-:.no corrosion or loss of power in a sealed system.

 nickel anode must be whole nickel straight through,not plated.you can substitute a piece of silver 925 jewellery for nickel.etch it in nitric acid before use to roughen.

A nickel mesh can also be extracted from a NiMH battery.the mesh is surrounded by black NiO2 and must be shaken a bottle with lots HCl pool acid to take off the coat and expose clean nickel mesh.
