Electroplating battery open source invention noble metal fuel cell hybrid

Edit: 6/9/16 It looks like germanium has failed testing.  Voltage was 0.6v with gold in 37% hcl with no oxidizer and the voltage dropped with oxidizer.  No amps could be generated.  I don't have high hopes that under any conditions could germanium beat copper in this battery.  I did also confirm that the cathode needs to be oxidized and the anode reduced.  Perhaps the battery will be two parts separated by any type of divider and oxygen on the cathode side and hydrogen on the anode side.  The divider should help restrict the dissolved gasses crossing from one side to another but the divider is optional.  Sparging can also be used.

This is another perspective on the noble metal battery.  The electroplating battery is any battery that discharges by dissolving element(s) from the anode into the electrolyte solution and charges by electrodeposition of the element ions back onto the electrode during recharging.  The electrolyte can be aqueous or non-aqueous.  Aqueous electrolytes work when the anode element to be deposited has a potential greater than water's potential.  Water's potential is around 0.2-0.6v so metals with a potential over that can easily be deposited using an aqueous electrolyte.  If the metal is below that, as is the case for germanium, you can add hydrogen gas to the electrolyte to bring waters potential down to -0.6v.  This will allow for the electrodeposition of germanium.  For anode metals with a negative potential; an acidic electrolyte is not possible to use because hydrogen ion potential is 0 which is higher than the anode so it would self discharge.  So a non acidic salt needs to be used.  Also chlorine ion's potential is -1.3 roughly so a metal like aluminum wouldn't be able to use a chloride salt.  Luckily fluoride salts have a roughly -3 potential so sodium fluoride dissolved in a non aqueous solvent can accommodate even magnesium which is -2.6.

Oxygen gas added to the electrolyte during discharge can greatly increase the amount of amperage that can be drawn.

So for a germanium iridium battery (or any cathode) it would preferably require both an oxygen tank and a hydrogen tank as well as a vacuum pump for optimum efficiency.  This battery should develop a maximum of roughly 1.6v

The benefit to electroplating batteries is with proper maintenance they should never degrade and can be reused indefinitely.

To prevent unrestricted dissolution of the anode, the anode element(s) can be plated onto a more resistant element(s).  Once the anode elements(s) (including multiple layers of the same or different anode materials) is dissolved off the cathode the current stops.  This means you could have anode and cathode both the same material but a layer of extra material coating one electrode and that extra material being the anode.

*Voltages are quoted at 37% hcl with oxygen/h2o2 ubless specified otherwise.  Hydrofluoric acid and/or higher concentrated HCL may improve voltage.
