In addition to the systemic meta-study, further deep dives were provided by the study authors umlaut SE and the Fraunhofer IPT. In the first two deep dives, the 7-layer membrane electrode assembly (MEA) and the bipolar plate (BPP), the largest cost drivers of the PEM fuel cell stack, are addressed. Different materials, process flows and the resulting cost structures are explained, thereby providing an overview of the complex components.
The following was presented in detail:
- Component function
- Material selection
- Manufacturing process
- Value chain
- Component costs
Both the meta-study and the deep dives are intended to serve as a basis for discussion within the industry and to provide a general overview of fuel cell technology. In addition to the configurations and manufacturing alternatives shown, other features and product characteristics are conceivable.
