Nanoparticle-Substrate for fuel cells, electrolyzers, and chemical reactors and sensors

By electrodeposition of crystalline nanoparticles onto a conducting substrate (for example a PTFE enhanced carbon fiber ultrahydrophobic sheet) for the first-time, it becomes possible to selectively create platinum-nanoparticles of the size of about 2 nm onto the bumps of the substrate without agglomeration. One advantage of this procedure is that diffusion through ultra-hydrophobic pores into inner gas conducting structures is avoided. The major benefits consist in the reduced need of platinum and a decreased number of process steps for the production. Possible applications of this technology are: all types of polymeric-electrolyte fuel cells (PEMFC, HT-PEMFC, DMFC, DEFC), all types of electrolyzers (H20, NaCl, HCl, etc.), electrochemical sensors and chemical reactors (consumable hydrogen anode, consumable oxygen cathode, etc.).
