A new and environmentally friendly liquid electrolyte gas sensor

For the purpose of making an electrochemical sensor for CO gas detection, by mixing an ion conductor into the catalyst layer and by unique application of a separator, the amount of noble metal catalyst and the density of electrolyte can be reduced. The result is a new electrochemical CO gas sensor possessing improved characteristics with the advantage of being more environmentally friendly, made possible by a neutral/very low concentration alkaline electrolyte and an extremely low amount of noble metal catalyst.
