In this paper, the effectiveness of support schemes for micro fuel cells in Germany is analyzed with regard to the latest market conditions, technical characteristics, and legislative changes. To this end, a dynamic model is used and applied to high-resolution household demand data. Specifically, we scrutinize whether polymer electrolyte membrane fuel cells are now a feasible investment option for residential usage in Germany or are likely to become so soon. Furthermore, we investigate whether electric energy storage could be a useful extension to the domestic fuel cell system by supplying short-term peak demand, and thus increasing self-consumption and potentially the overall economic merit. We find that the fuel cell technology analyzed is unlikely to become cost-competitive by 2020, and it may take quite some time to achieve a substantial market diffusion. We conclude that for the time being, electric energy storage in combination with a fuel cell system is not a worthwhile investment in a scenario where grid connection is assumed.
