So, i am trying to figure out the Thermodynamics of H2 adsorption onto a metal hydride. I need a bit of assistance if anyone knows these equations.
First off, since my MH alloy is the negative electrode in an electrolysis cell i use this equation DeltaT<(1/4D)-(Xad/x)^2 to figure out the percentage of protons on the electrode. To do any further equations i need to figure out the density of H2 ions on the surface of the Metal Hydride per 300ns.
The equations i need to do are:
MHydride reaction: M+x/2H2 <--> MHx+Q
Q=Temperature in Kilajoules/mole(g)
x= concentration of H2(moles/g)
A=Hydride forming substance
B=Non-hydride forming substance (lattice scaffold if you will)
n= atomic number of B atoms to every single A atom in the alloy alttice
Where since i am using an AB5 metal hydride the equation i need to use is ABn+(x/2)H2[@Pressure determined by the gibbs function]<---> AHx+nB+Q to figure out the overall concentration of Hydrogen into hydride state upon exposure of the 2 components (M+H2) to pressure. Different alloys require different pressures.


Once i know the thermodynamic characteristics of the particular alloy that i am working with, i can design a chamber ideal for producing the Metal Hydride reaction over many cycles. Once i know the relative H2 concentration on the cathode per pulse (each pulse being 300ns) i can figure out over, say 1 minute how much H2 migrated into the metal alloy electrode, as well as how much heat and pressure are needed to recover the H2, and to cause the MH reaction. Thus the feasibility of creating the device in-mind increases as i will know the exact parameters for the device to operate within (even under strictly ideal equations, the natural losses can be mitigated with a 5-10% scale, so increase pressure or temperature 5-10% what the equations say to make up for natural losses in the process. Whether ohmic, thermal, material etc.

What kind of device would i need to control the charge flow between a battery, a load, and a generator. Where the battery powers the load and the generator charges the battery when it discharged. How would i build this control sequence into a small circuit, say with a Raspberry Pi?

Essentially the circuit flow is this: A hydrogen fuel cell powers an electric motor (inductive load) while an on board generator charges up a battery. I need a circuit that allows me to discharge the battery through the motor when the fuel-cell doesn't have access to hydrogen, and switch the the fuel cell if the battery is dead. While the generator charges the fuel-cell fuel source when dead (battery powers motor) then when the battery is dead and fuel cell is charged the process reverses where the battery is charged by the generator and the fuel cell powers the load. What kind of circuit do i need to control this?

It has two power supplies a 36V hydrogen fuel cell and a 24V battery. The FC is for cruising speeds and the battery is for sharp acceleration and start-up. When the switch is closed the fuel cell will power the motor and force the Schottky into a reverse bias, which prevents the battery from discharging (as well as can be expected) through the circuit. This set's up a voltage differential within the op-amp (comparator) which activates the op-amp to send current from the generator into the battery. Power source can be from back-emf circuits or from a wheel connected generator or another battery. When the FC switch is open the battery discharges into the motor and the op-amp closes the current between the generator and the battery and instead sends the generators current into an electrolyzer to create and store H2 (this can be toggled on and off) Essentially the circuits is supposed to allow control over discharge and recharging of current sources for a DC motor.

Any thoughts?
