Is this true?

No, inexhaustible is like perpetual motion or anything that you want to make that runs forever it can’t happen.
This is due to a property of the universe called entropy where systems tend to break down to a chaotic state. The Earth won’t revolve around the sun forever, in 4 billion years or so it will blow up, the universe won’t run forever either at some point billions and billions of years from now it will be destroyed in the heat death of the universe. One of the few absolute rules in nature is the NOTHING lasts forever.
In your system whatever produces the ions would be eventually destroyed and through inefficiencies like resistance it would eventually drain away. No matter how tight you make the system failure will creep in there somewhere because of the law of dimensioning returns; you can never get anything for free.

A little elaboration on danielg33125's answer. Technically, a fuel cell is not a battery. A battery is self contained, while a fuel cell has fuel and oxidizer continually added to it, as needed.

No. Certain molecules leave the battery during it's lifetime never to be replaced. Chiefly among these would be Hydrogen molecules (in it's gaseous state).

...er...yeah...battery companies just haven't bothered to get rich off this simple idea, and no one else has thought of it...suuuuuuure.

no, reactants will leave the reaction and you need to refill the reactant.
