French Nuclear Research Center

The French Nuclear Research Center CEA announced the successful fabrication of high performances prototypes fuelled by H2 and based on thin films type structures on Si substrate obtained by micro-electronics fabrication techniques (RIE for fuel micro-channels, PVD for anode collector, CVD, serigraphy, inkjet for Pt catalyst, lithography) with a Nafion membrane [15]. An impressive power density of 300 mW cm with a stabilisation around 150 mW cm" during hundred hours was reported. 

Monomers with low molecular weights will diffuse into the wood more rapidly than polymers such as PEG. In a second phase, their in situ radiation curing will form wood consolidants that are much stronger than PEG. However, this method requires very heavy irradiation equipment, which is usually available only in nuclear research centers. The irradiation cell dimensions and the 7-source geometry limit the size of the artifacts. For mainly these reasons, the radiation process was applied in very few institutions and in most cases only at the experimental level. The Nucleart Laboratory, which routinely conserves waterlogged wood by this technique, is located in the Grenoble Nuclear Research Center of the French Atomic Energy Commission.
