Chemical hydrogen generator
type 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 GIP™ 3 type hydrogen generator cartridges are
stored in waterproof metal boxes made of quantitative
dosage of:
• alkaline cartridge,
• priming cartridge,
• granulated silicon cartridge.
A manipulation allows the generation of 3 Nm3 of
hydrogen volume within 30 minutes.

H2 GENERATOR TYPE BPMP

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.

RESULTS OF FRAUNHOFER PEM TESTS
• 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
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
