Optimized BM: synthesis, ex situ characterization and testing in BMFC and BMEL

Summary
The document will report on the conductivity and stability properties obtained with the optimized BM developped during CREATE. While the full synthesis and structural characterization of these optimized BMs will probably not be divulgated in this public report for IP reasons, the conductivity and stability of these optimized BMs will. These properties will have been measured ex situ and also in situ in BMFC and BMEL.
