More Information
Summary:A process and an apparatus humidify process gas for operating fuel cell systems. To ensure high efficiency, the process gas must be introduced at a predetermined temperature and humidity. A metered quantity of fine water droplets is injected into the gas supply line, by way of which the process air is humidified. If the fuel cell is operated under pressure, the process air generally has to be cooled after it has been compressed. The process air is automatically cooled as a result of a partial evaporation of the water droplets while the residual quantity of water in the form of droplets is introduced into the fuel cell.
