WebBorophosphosilicate Glass. ... When SiH 4 is cooxidized with PH 3, films of phosphosilicate glass (PSG) form, but reaction with PH 3 + B 2 H 6 mixtures generates BPSG. The role of phosphorus is to getter or trap the mobile ions, while boron “softens” the layer facilitating viscous flow and planarization during reflow annealing. WebJun 1, 2012 · Highlights H 2 /O 2 fuel cells equipped with proton-conducting Nafion ® /phosphosilicate (NPS) glass membranes, which are prepared from phosphosilicate glass and a perfluorosulfonic acid polymer, are characterized. The fuel cell performances are improved step by step by using Nafion ® resin as an adhesive, increasing operation …
