Besides aspects like lifetime, efficiency or environmental compatibility, the question of the attainability of given cost targets is of paramount interest in fuel cell technology. Therefore, a major aim of this PhD thesis is to develop a universally valid techno-economic cost model for components of PEFC stacks in the kilowatt range. Different technical solutions will be comparable with regard to their corresponding production costs - based on the concept of "benchmarking" management. Determination of mass-specific production costs takes on a key role. The utilization of a MONTE CARLO approach is a novel procedure delivering expectation values as well as confidence intervals for the material costs of the stack components. Consideration of production costs incorporates the fabrication conditions of individual components. The new methodology is first applied to the injection moulding of composite plates as one of several new technologies for producing bipolar plates (BPP). Furthermore, detailed cost analyses of five common ionomers constitute the main technological focus of the thesis in view of the complexity of ion-conducting polymer membrane production and the difficulties customers would have in assessing this process. The material cost of platinum-based catalysts outweighs their production aspects in a cost analysis, at least under present conditions. The following table gives an overview of the main results of the planning calculations at full cost (pp. 90, 141): [Abb.] From a strategic point of view, such accompanying process cost calculations can undoubtedly contribute to a faster recognition of the cost potential of promising fuel-cell materials and component technologies. Limited R & D resources can thus be focused more efficiently on the commercial success of the innovative fuel cell technology. |
