Abstract |
Abstract of the invention An improved filter-press type high pressure alkaline water electrolyser cell module. It consists of end flanges loaded and biased by belleville springs and half cell units located on the end flanges insulated therefrom by insulator plates. A plurality of cell units is located between the half cell units. The cell units are stacked in series and insulated and isolated from one another and from the half cell units by diaphragm gaskets- The end flanges, insulator plates, half cell units, cell units and diaphragm gaskets are held together by tie rods. Each of the half cell units consists of a monopolar plate formed of an electric conductor metal sheet having a terminal and provided with a recess having a step at the peripheral wall thereof at one side of the sheet. The space between the periphery of the recess and the periphery of the sheet forms a peripheral rim. Each of the cell units consists of a bipolar plate formed of an electric conductor metal sheet provided with laterally staggered recesses having steps at the peripheral walls at both sides of the sheet. The space between the peripheries of recesses and the periphery of the sheet forms the peripheral rim- A porous electrode is located in each of the recesses against a flutted screen mesh and the respective step. The space between the bottom of the respective recess and porous electrode forms electrode chamber. The pdYotis electrode consists of an electrode metal porous plaque _lpjĀ£ated in between an electric conductor metal inner ring and an electric conductor metal outer ring. The outer ring is flush with the plaque at both sides thereof. The end flanges, insulator plates and diaphragm gaskets are provided with corresponding electrolyte entry ports and gas exit ports* The monopolar plates and bipolar plates are provided with electrolyte inflow channels and gas outflow channels through the rim registering with the electrolyte entry ports and gas exit ports respectively. These channels are connected to the electrode chambers by electrolyte inflow passages and gas outflow passages provided through the rim. |
