An electrochemical gas generator is provided with an electrolysis cell ( 1 ) with a housing, which is closed by a gas-permeable membrane ( 2 ) for the escape of the test or calibrating gas. A cathode ( 5 ) is provided formed of a noble metal, a mixture of noble metals or a material containing carbon. The cathode is in direct contact with an electrolyte ( 7 ) disposed in the housing. An anode ( 4 ) is provided formed of a noble metal, a mixture of noble metals or a material containing carbon. The anode is in direct contact with an electrolyte ( 7 ). The electrolyte ( 7 ) contains a carboxylic acid salt. A control unit ( 6 ) is provided that acts as a current source and which is connected to the electrodes ( 4, 5 ).
