anything but irrelevent.this shit is going down.this is shit you can measure in your lab like i said namsayn but i cnt exactly prove that from a video-tape.your gona have to trust the nernst equation and also what wikipedia said bowt entropy preferences under title 'concentration cell'

its gota be perfect so we want the best text-cites namsayn @sarkeizen.chill for a while..brb

According to you it's in every textbook everywhere in a form that leaves no room for question....

I think you were kind of lying about that.

How hard can this be?  You said it's in every electrochemistry textbook but you can't just go and open one.  Find the thing you are talking about.  Write down the page number and the title of the book.  Then type those things here.

Seriously.  Are you crippled in some way that you haven't discussed?

I think that this statement neatly embodies a great deal of the misconception:

so lets go with the textbook flow your highness sir-sarkeizen: the corrosion textbooks say that the oxygen concentration potential will keep rusting the point on the iron,steadily,continuously,over days,months,years,tens of years.this sound like a persistent potential to you? Sounds like a persistent potential to me.with total complete gaseous communion.(try a rusting experiment sometime).thus we safely conclude the standardised equi-pressure oxygen gas concentration cell to posess a permanently stable nernstian rest potential,in breach of kelvin laws.   

The statement ignores that absent a steady supply of fresh oxygen, the oxygen reduced into oxide depletes just as the supply of unoxidized iron declines.  Whether the battery runs out of oxygen or iron first, it winds down.  Profitis' concept for a perpetual battery seems to depend on the availability of an infinite supply of feed stock reactants.

totaly incorrect @mark E.i said differential aeration corrosion relies on a constant oxygen concentration gradient potential to work,with free communion of gas,in gross contrast to your earlier statement about oxygen concentration potentials with communion.the galvanic action of the iron having nothing to do with the creation of the aeration differiential potential,in fact only emphasising my point of a stable nernst o2 potential at rest regardless of gas communion. You also failed to defend yourself by explaining why 2 totaly seperate pieces platinum sitting at different depths in electrolyte under one atmosphere pressure will not measure equal potential in seperate boxes against a reference electrode but will (according to you) register the same potential under a joined box under one atmosphere.
