本文的目的是研究泡沫镍电极在经典压滤式电化学电池中的应用。为此目的，已使用由Electrocell AB商业化的ElectroSynCell®。使用连接到经典平板的金属泡沫的兴趣在于通过增加电极表面积来改善电化学电池的性能。此外，对于某些工业应用，可以使用没有膜的电池。在所提出的配置中，工作电极由连接到平板的金属泡沫组成，辅助电极简单地是平板。工作电极和辅助电极的表面积之间的不平衡允许使用单个液压回路进行操作。本文着重研究停留时间分布和压降，以便与经典配置中的流动行为进行比较。文中还给出了电池反应区的模型。
The aim of the present paper is to investigate the application of nickel foam electrodes in classical filter-press type electrochemical cells. For this purpose the ElectroSynCell®, commercialized by Electrocell AB, has been used. The interest of using metallic foams linked to a classical plane plate is to improve the performance of the electrochemical cell by increasing the electrode surface area. Moreover, for some industrial applications it is possible to use the cell without a membrane. In the proposed configuration, the working electrodes consist of metallic foam linked to a plane plate and the auxiliary electrode is simply a plane plate. The imbalance between the surface areas of working and auxiliary electrodes allows operation with a single hydraulic circuit. This paper, focuses on the study of residence time distribution and pressure drop in order to compare the flow behaviour with that in a classical configuration. A model for the reactive zone of the cell is also given.
