イオン交換膜を用いた電池に関する研究（第11報）Mass transfer for the following electric cell was studied, ⊖ Fe/FeCl₂ sat. soln. / 1N or 5N HCl /Pt-black Pt/Ti ⊕. M_ Electric energy can not be only gained but also hydrogen H₂ (a clean fuel gas) and ferrous chloride FeCl₂ (Chemical product) can be produced by this multipurpose cell, utilizing spent acid HCl and iron or steel scraps. The water tranfer was taken place from the positive apartment to the negative one in any case of utilizing 1N HCl or 5N HCl. These behaviors were as same as the results obtained by N. Laksh-minarayanaiah. It was found that mild steels could be dissolved well into the saturated FeCl₂ solution as a catholyte of the cell. As Fe⁺⁺ ion could be transferred through the anion exchange membrane (M₋) at lower discharge current density, the higher was the discharge current density, the higher was the producing efficiency of FeCl₂. In any case, the treatment efficiency of spent acid (HCl) was more than 100%, because H⁺ ion could be transferred easily through the membrane (M₋) by diffusion. According to the discharge characteristics, the producing efficiency of FeCl₂ and the treatment efficiency of spent acid HCl for this cell, better results were taken with 5N HCl as an anolyte of the cell.
