Title:
METHOD FOR DEPOSITING A CATALYST
Document Type and Number:
WIPO Patent Application WO2002052663
Kind Code:
A3
Abstract:
The invention relates to a method for depositing catalyst material, especially for deposition in a membrane electrode unit (MEA) for a fuel cell. According to said method, the deposition takes place in situ from a precursor layer, directly in the fuel cell. This simple method advantageously saves expensive catalyst material and enables the distribution of the deposited catalyst to be optimally adapted to the respective fuel cell.
