利用膨胀网作为双极板流道结构优化碱性水电解槽OA北大核心CSTPCD
Optimization of Channel Structure of Alkaline Water Electrolyzer by Using an Expanded Mesh as a Bipolar Plate
碱性水电解制氢是现今最为成熟的水电解制氢技术.电解槽由多个电解小室组成,单个电解小室由隔膜、电极、双极板和端板等组成.现有工业的双极板流道结构为凹凸结构,通过模具冲压成型制备,制备成本高且困难.凹凸结构电解小室存在电解液流动不均匀和电流密度低的问题,进而增加了碱性水电解制氢的能耗和成本.因而,本文首先根据现有工业的凹凸双极板流道结构搭建电化学和流动模型,分析电解小室电流密度、电解液流动和气泡分布情况.模型可靠性已通过与文献实验数据对照验证.其中,…查看全部>>
Alkaline water electrolysis(AWE)is the most mature technology for hydrogen production by water electrolysis.Alkaline water electrolyzer consists of multiple electrolysis cells,and a single cell consists of a diaphragm,electrodes,bipolar plates and end plates,etc.The existing industrial bipolar plate channel is concave-convex structure,which is manufactured by complicated and high-cost mold punching.This structure still results in uneven electrolyte flow and …查看全部>>
