OPERATING PRINCIPLE
Chemical hydrogen generatortype GIP™ 3
The process of hydrogen production with the GIP™ 3 generators is based on the attack of silicon by the caustic soda in aqueous solution under pressure and high temperature.
Its production per cartridge is 3 m3 of hydrogen (measured in conditions at 15 °C and 760 mm of mercury).
The caustic soda undergoes the action of pure
silicon in autoclave.
Pressure is produced by the reaction itself, which is not reversible.
A local rise in temperature enables the liquid to reach a temperature high enough to compensate fully the retarding action of the pressure and to insure that the pure silicon is completely attacked.
The hydrogen is stored into the cylinder at high pressure.

The hydrogen and oxygen are produced at atmospheric pressure by one or several electrolysis cell serial connected
Each electrolysis cell is made of one anode electrode (oxygen production), one cathode electrode (hydrogen production) and one diaphragm (separation of oxygen and hydrogen).
The oxygen produced is directly evacuated into the atmosphere.
The hydrogen is stored at 5 millibars in the movable bell of the gasholder which is filled when gas is produced.
When the bell is full, the hydrogen is transferred from the gasholder to a storage tank by means of a hydrogen compressor.
The compressor automatically stops as soon as the gasholder bell is empty.
The compressor automatically re-starts when the gasholder bell is full and then stops; the same operating principle occurs until the complete filling of the storage tank.
The system will restart automatically after the filling of a second balloon in order to maintain full the hydrogen tank.
A water treatment system including a 20-liter demineralized water tank allows to make the periodical electrolyte level in the electrolysis cells.

H2 GENERATOR TYPE MP8
H2 generator type MP 8
The hydrogen and oxygen are produced at atmospheric pressure directly under pressure by two electrolysis cells serial connected.
The electrolysis cell is made of one anode electrode (oxygen production), one cathode electrode (hydrogen production) and one diaphragm (separation of oxygen and hydrogen).
The hydrogen and oxygen produced are directly steered to a pressure balancer.
The pressure balancer has 4 level control probes, each of them having a role:
Safety by oxygen overpressure sign of leak in the hydrogen circuit
Safety by hydrogen overpressure sign of leak in the oxygen circuit
Oxygen / hydrogen pressure relief necessary for the automatic recovery of the electrolyte levels inside the cells
Level control cyclic extraction of the oxygen into the atmosphere
The hydrogen produced is directly transferred towards the storage tank through a weir and a sized hole allowing a flexible and homogenous filling.
The equipment automatically starts again after the filling of a second balloon so as to fill again the storage tank.
The periodical electrolyte level in the cells is automatically restored by adjunction of demineralized water.

• Tests of the generator between May and October 2007
• After 400 Hours of functionning :
Stack out of order Strong corrosion of the H2 side, Ti membrane,
electrode Plates made from plastic OK
• Today : Modifications of the regulation system by
Fraunhofer Replacement of the cells stack by Fraunhofer Beginning of new reliability tests at the end of
january by SAGIM
RESULTS OF FRAUNHOFER PEM TESTS
To Resume :
CETH Technology:
- Good production range- Generator and stack of cells too
expensive - No real experience return on the stack- Maximum pressure 30 bars
Fraunhofer Technology :
- Maximum production too low (110L/h)- Lifetime of the stack too short (400h)- Easy use
Prospects : - Utilisation of a phosphate solution to replace alcaline
solution - Better electrolysis energy efficiency
