2 COVER PHOTO: Center: Diagnostics are essential for fuel cell development. The picture shows a collage of different spatially resolving in situ methods simultaneously applied to a fuel cell. The base is formed by a neutron image showing the water distribution within a small scale PEFC. The larger curve shows the local current generation, and the winding curves are representations of the local impedance response of the device. From the combined measurements, detailed information about local processes and limitations can be obtained.

50 On the occasion of the 57 th Annual Meeting of the International Electrochemical Society 2005 in Busan, South Korea, a joint Seminar between PSI and RCECS (Research Center of Energy Storage and Conversion) was held at the Seoul National University (SNU). Some impressions from our spirited annual Christmas party
