  • Patent number: 5650058
    Abstract: The invention includes an electrolytic cell for gas-developing or gas-consuming electrolytic reactions and processes, and an electrolysis process therefor. According to the invention, the capillary slit electrode has conduits enabling the separate flow of reaction gas and electrolyte/permeate in the electrode. The electrode is preferably hydrophilic in a narrow internal region for mounting on a separator, while elsewhere it is hydrophobic. Thus electrolyte/permeate penetrates only into the region of the capillary slit electrode near the separator, while the region away from the separator remains free of electrolyte/permeate, so facilitating the unimpeded flow of the reaction gas. The invention is applicable especially in electrolytic cells for chlor-alkali or hydrogen electrolysis, and in the construction of cells for the generation of power.

  • Patent number: 5498826
    Abstract: The present invention refers to a plasmatron as well as to a process for stable operation of plasmatrons with steam as the plasma gas, in the case of which the operational fluctuations which are typical of steam plasmas as well as the increased degree of electrode erosion are to be avoided. In accordance with the present invention, this is achieved on the basis of a limitation of electrode cooling by using hot water as a coolant having a temperature of at least 80.degree. C. If necessary, it is possible to use, on the one hand, hot water cooling and to exclude, on the other hand, a condensation of the steam on the electrodes by admixing a gas which will lower the condensation temperature of the steam.
