Abstract:
A wetting process, which comprises the steps of:providing a fuel cell having electrodes with a gas-side surface, an electrolyte with at least one surface, and at least one channel body with at least one semi-permeable membrane disposed above the electrolyte, the channel body directly contacting the gas-side surface of at least one of the electrodes; providing a fluid containing a wetting agent in the channel body of the fuel cell, it being possible for at least some of the wetting agent to pass through the semi-permeable membrane of the channel body to reach the electrolyte; providing the fluid with air as a carrier medium and carrying the wetting agent in the carrier medium; and metering an amount of the fluid to be supplied to the electrolyte in dependence on a type of the fuel cell used and on parameters which can be adapted to a particular fuel cell configuration.
