Page 6: Description
Hydrogen Generator NM Series 2 User’s Manual Description The hydrogen generator produces pure hydrogen (and oxygen as a by-product) by the elec- trolysis of water. The key element of the generator is an electrochemical cell assembly which contains a solid polymer electrolyte. No free acids or alkalines are used. De-ionized or pure, distilled water is the only liquid which may come into contact with the cell. -
