Phosphoric acid functionalized pre-sintered meso-silica for high temperature proton exchange membrane fuel cells.
An inorganic proton exchange membrane based on sintered mesoporous silica and phosphoric acid was developed with a high proton conductivity of 0.06 S cm(-1) at 200 °C, achieving an excellent power output of 689 mW cm(-2) in H2 at 190 °C and 200 mW cm(-2) in methanol at 200 °C with no external humidification.

متن کاملHigh frequency sonoluminescence in sulphuric acid and phosphoric acid
Multibubblesonoluminescence (MBSL) emission spectra at different forcing frequencies ( 20, 580, 850 KHz and 1.1 MHz) in Sulphuric acid and Phosphoric acid, under different noble gases atmosphere ( Ar, Xe and He) have been investigated. Using lower frequency we observed the presence of new emissions lines which may indicate the formation of ionized species with very high energy level inside the ...
متن کاملThe Recovery of Uraniumfrom Phosphoric Acid
Commercialization of three processes (OPPA, DBPA-TOPO and OPAP) has shown that the DEPA-TOPO process offers the best technology available today for the recovery of uranium from wet-process phosphoric acid. Uranium recovery plants using this process have been successfully operated in the United States, Belgium, Canada and Taiwan. Operating experience from these plants has led to a significant re...
