Humidifying membrane modules

  • Humidifying membrane modules
  • Humidifying membranes for fuel cells currently manufactured by NOK are hollow fiber membranes with nano-order pores provided on the membrane surface in our unique composition design. When air containing water vapor (wet gas) is brought into contact with the membrane, the water vapor is condensed to water in the pores and returned to vapor on the inner surface of the membrane according to the capillary condensation theory. The vapor is then fed to the fuel cell stack by supplied air (dry gas).
