Anomalous hydrogen generation by plasma electrolysis

摘要

Direct decomposition of water is very difficult in normal conditions. Hydrogen gas isusually obtained by the electrolysis. Pyrolysis decomposition of water occurs at high temperatures,starting at ～3000°C. As we have already reported, anomalous hydrogen is sometimes generatedduring plasma electrolysis. Excess hydrogen usually appears once certain difficult conditions duringhigh temperature glow discharge electrolysis are met. Here, we show that anomalous amounts ofhydrogen and oxygen gas are generated during plasma electrolysis excess gas generation,presumably from pyrolysis. This is indirect proof that exceptionally high temperatures have beenachieved. (Direct measurement of the reaction temperature has proved difficult.) Continuousgeneration of hydrogen above levels predicted by Faraday's law is observed when temperature,current density, input voltage and electrode surface meet certain conditions. Although only a fewobservations of excess hydrogen gas production have been made, production is sometimes 80 timeshigher than normal Faradic electrolysis gas production.
