Atmospheric pressure water vapor, in the temperature range from 150 to 700 °C, was used as the carrier gas for DC powered electrical discharge in hollow cathode configuration. The electrode assembly was constructed in usual hollow-cathode configuration by sandwiching a dielectric spacer, 200 μm thick, with two thin metal sheets and boring a micro hole of 300 μm diameter. The current–voltage profile of the discharge showed a positive differential resistivity characterizing an abnormal glow discharge. The power consumption for the water discharge at 700 °C was less than 50% the consumption at 150 °C. The reduction of the power for sustaining the discharge with increase of the gas temperature was partly explained by relating the ionic mobility and the distribution of ionic mean free path to the temperature.
