The most widely used materials for GDL are Vulcan XC- 72R, pearl black, acetylene black and Ketjen black. 这是一篇有关燃料电池电极的文章请详细介绍一下这几种Vulcan XC-72R，pearl black, acetylene black and Ketjen black。 ( Accordingly, the fabricated porous carbons happen to be the structural replica of the hard template. In this process, an additional step is mandatory to prepare silica templates prior to the multistep template synthesis making it a long and complicated process . Therefore efforts have also been made to synthesize OMC materials without the hard template route . Although, these classes of MCs show some irregularly interconnected pores and relatively wider distribution of pore sizes than OMCs, their synthesis is simple and mesoporous structures can be controlled by varying the molar ratio of the respective precursors.) [ The study includes the synthesis of OMC structures based on commercially available tri-block copolymer (pluronic F127,EO106PO70EO106) as a structure directing agent and a mixture of phloroglucinol and maldehyde as a cost-effective carbon precursor by a sol–gel route.] |
