Abstract

Изобретение относится к электродиализной ячейке для растворов солей для производства соответствующих кислот и оснований путем способа, который имеет сниженное или нулевое потребление электроэнергии. Ячейка содержит анодную камеру с подаваемым водородом, и катодную камеру с подаваемым кислородом или воздухом и оборудована соответствующими газодиффузионными электродами; движущая сила способа электродиализа создается за счет химических потенциалов окисления и восстановления водорода и кислорода, подаваемых в две камеры.
