Innovative production technique for PEFC electrodes
- Institut fuer Technische Thermodynamik, Stuttgart (Germany)
Fuel cells are high efficient and low polluting energy conversation devices. Using hydrogen as a fuel gas they are applicable to solve environmental problems e.g. CO{sub 2} impact on the climate. Thus international research efforts have been increased in recent years. Low temperature fuel cells e.g. the PEFC are specially applicable for future transportation and stationary energy supply systems. Application and economics success of his technology is obstructed by the high investment costs with respect to conventional energy conversion devices. The intent of our activities is the improvement of electrodes and membrane-electrode-assemblies as used in PEFC. Commercial and technical aspects of electrode manufacturing have been considered in early stages of the development of the production procedure. Two different techniques are developed at DLR. The first is a rolling procedure as used for production for batteries and alkaline fuel cells which has been modified and adapted to the specific demand of PEFC electrodes. The second technique is a new printing process to produce ultra thin layers of catalyst directly on the electrolyte. In this paper we will show the first results of the first electrode technique which have been tested in fuel cells and a short description of the second very new method.
