PRECISION MEASUREMENT OF EXCESS ENERGY IN ELECTROLYTIC SYSTEM Pd/D/H2SO4 AND INVERSE-POWER DISTRIBUTION OF ENERGY PULSES VS. EXCESS ENERGY

Excess energy was measured with a Seebeck envelope calorimeter in an electrolytic system containing a 2 mm diameter Pd tube cathode. After about 50 hours of electrolysis, many power pulses (Pex < ∼0.5 W) and bursts (Pex > ∼0.5 W) of excess power Pex were observed. The distribution of the number of power pulses N(Pex) with definite excess power Pex plotted on a logarithmic scale is expressed as a straight line with a gradient ~ – 2 for Pex < ∼0.5 W showing the typical behavior of the 1/f noise. The distribution for Pex > ∼0.5 W deviates from this regularity. These characteristic behaviors are discussed in relation to complexity in the mechanism of the excess energy generation in the experimental system.
