H₂ Plants

Gaslabs designs and supplies complete hydrogen gas plants with cylinder filling facility. On small scale hydrogen is produced from electrolysis of water in either Knowel’s type mono polar cells or filter press type bi-polar cells known as electrolysers.

Knowel’s type Electrolytic Cells

• Tanks and bells are welded by special quality electrodes to avoid Hydrogen and Caustic soda    embrittlement.
• Bells are manufactured out off C.R.C. Sheets which are specially recommended for Caustic soda    handling.
• The Asbestos diaphragm cloth is manufactured from 100% pure long fiber asbestos without    cellulose core and closely woven to avoid pin holes.
• Extra length of cloth is provided at the bottom to guard against bye-pass of gases.
• Ebonite Insulators are tested against warping under high temperature and they are checked by    Meger for infinity resistance.
• Nickelling of Anodes is done under strict supervision for a minimum of .002 thick coarse deposits    and each plate is tested chemically for pores.
• The bells are fabricated by special fixtures and pneumatically tested to avoid leakage.
• Side plates of bells are welded to avoid leakage.
• Each Electrode plate is made straight by special Jigg and all the plates are perfectly parallel when    assembled.
• The 1" pipes are fixed on the bells with the help of a special Jigg to enable all the tubes to be    equidistant and parallel for quick and easy fitting of the electrode plate.
• Each Electrode plate has two full-length copper rods.
