Tanzella, Godes, Liu and George report calorimetry on Brillouin Energy's coated ceramic catalyst tubes in hydrogen, stimulated with nanosecond pulses across the coatings. The Energy Research Center has verified this calorimetry for over 18 months, since 2 calorimeters moved from SRI International to Brillouin's laboratory. Pulses of several hundred volts lasting tens of nanoseconds concentrate current at the outer metal-ceramic interface through the skin effect. Pulse power is measured with fast oscilloscopes, and a system identification heat-flow model built for this calorimeter tracks power reaching its five temperature sensors. Between 200 and 350 °C in hydrogen, the stimulated catalyst substrates produced thermal power, comparing heater-only runs with heater plus pulse runs.
