Electrochemical gas generator for hydrogen sulfide comprises an electrolysis cell with a housing having a gas-permeable membrane, an anode, a cathode and a control unit acting as a current source and connected to electrodes

摘要

Electrochemical gas generator comprises an electrolysis cell (1) with a housing having a gas-permeable membrane (2) for the output of a testing or calibrating gas, an anode (5) made from a precious metal, a mixture of precious metals or a carbon-containing material in direct contact with an electrolyte (7), a cathode (4) made from a precious metal, a mixture of precious metals or a carbon-containing material in direct contact with the electrolyte and with a mixture of metal sulfides and sulfur and a control unit (6) acting as a current source and connected to electrodes.
