Anomalous excess heat in Pd|D2O+H2SO4 electrolytic cells was confirmed using an accurate method of heat measurement, Seebeck Envelope Calorimetry. A cell was placed in the calorimeter, which measures the output heat flux directly and avoids many of the problems other methods have. The maximum excess power thus far was 1.3 W (or 11 W cm  3 ) with input power of 13 W at a current density of 0.4 A cm  2 . Calibrations were carried out before and after electrolysis experiments using a

Pd cathodes were analyzed by scanning electron microscopy and energy dispersive spectrometry. Unexpected elements were observed on the sample surface after electrolysis.
