为解决商业化Nafion膜用于DMFC时出现的高甲醇渗透率[1],以聚醚醚酮(PEEK)为原料,浓硫酸为磺化剂,制备了一系列不同磺化度(DS)的磺化聚醚醚酮(SPEEK).然后以SPEEK、聚苯胺(PANI)和磷钨酸(PWA)为原料,采用溶胶－凝胶法制备了一系列SPEEK/PANI/PWA复合质子交换膜[2,3].XRD证明PWA以无定形状态存在于SPEEK/PANI/PWA复合质子交换膜中.
In this study,zinc oxide (ZnO) nanorods were used as efficient sacrificial template to fabricate nano-network structure (NNS) within anode catalyst layer (CL) and micro-porous layer (MPL) of a membran
A novel combined system integrated with SOFC/GT is proposed,which employs the double heat source Kalina cycle to recover the waste heat from SOFC/GT and the membrane separation of N2 or CO2 to obtain
Ceria based material is a promising electrolyte for intermediate temperature solid oxide fuel cell (SOFC) due to its high ionic conductivity and good chemical compatibility with traditional electrode
膦酸既是质子供体又是质子受体,是理想的质子传导载体.质子可以通过分子间动态氢键的形成与断裂,在膦酸分子之间完成传递,因此,以膦酸作为质子传导单元的质子交换膜的研究逐渐成为高温质子交换膜材料研究的热点[1-3].本研究选用3-氨丙基三甲氧基硅烷(APTMS)作为基体材料,以氨基三甲叉膦酸(ATMP)作为质子传导载体,将上述两种原料混合后,再添加一定量的聚乙烯吡咯烷酮(PVP),通过溶胶-凝胶法制备A
A novel combined power generation system driven by dual SOFC is proposed by using a Kalina cycle to recover the waste heat of exhaust from the dual SOFC/GT to improve the energy efficiency of traditio
The oscillation of combustion pressure is a classical phenomenon during the combustion process in most practical combustion devices,such behavior is always relevant to undesired combustion phenomena (
The effect of hydraulic retention time and influent alkalinity on the perfermence of bioelectrochemical system assisted anaerobic baffledreactor(BES-ABR)was investigated in this study.The system was o
For stand-alone solid oxide fuel cell(SOFC)power systems without grid connection,delivering demanded power,maintaining system temperature constraints,and achieving high system efficiency are the key d
In recent years,major research has been focused on alternative and renewable energy sources to replace our current reliance on fossil fuel.Some microorganisms can convert chemical energy from a wide r
