✦ Synopsis
A new planar chlorine micro-generator based on a solid-state electrolyte is reported. From the viewpoint of mass production, it has the following advantages: high accuracy and reliability, low cost of production by small amounts of noble metals and simple manufacturing procedures, ease of handling. The miniaturized calibration tool contains everything necessary to calibrate any chlorine sensor and portable or stationary gas detector. The general scheme of the micro-generator consists of a working electrode based on metals chloride, a counter electrode and a solid-state electrolyte with high proton conductivity at standard temperatures.
The principle of chlorine-gas production is defined by the electrolysis on the working electrode. The relevant technology developed allows the micro-generator to be kept to the dimensions 11 mmx5 mm with a mass of 4 g. The microgenerator can be installed in one block with the electrochemical solid-state micro-sensor for chlorine determination.
