France to develop ultra-low platinum content of the fuel cell electrode
MHS Equipment SAS ,France’s energy sector MHS subordinates June 9 announced that its manufacturing out of the ultra-low platinum content of the proton exchange membrane fuel cell electrodes (0.1μg/cm2).
The study was conducted in the University of Orleans Gremi laboratory, and the use of magnetron sputtering technology, platinum jet to its E-Tek ® gas diffusion layer.
Platinum particle size, sedimentary structure and platinum are in favor of the redistribution of redox reaction of hydrogen efficiency. Proton exchange membrane fuel cell electrode of the amount of platinum so low, and reached the 400mW/cm2. The use of Nafion ® 212 and Nafion ® 115 membrane experiments, respectively, the corresponding energy density fuel cells reached 0.4W/cm2and0.25W/cm2.
In addition to performance improvements, the cost of the technology ready and easy to industrialization on the fuel cell to generate a major promotion. The technology of the first batch of products will be named “TP2L2″, the content of platinum 20μg/cm2.
