Abstract
Electrical resistance measurements of gas‐charged alpha hydrogen‐palladium alloys have been made in the range 100° to 400°C. The fractional increase of palladium resistance caused by addition of hydrogen is proportional to hydrogen concentration. The constant of proportionality is independent of temperature, indicating that Matthiessen's rule is inapplicable to this system. When the results of this work are combined with those of previous authors, all of the data can be adequately represented in the range 75° to 400°C by the equation (R/R0) — 1 = (2.41±0.04) m, where R is the resistance of alpha hydrogen‐palladium, R0 is the resistance of hydrogen‐free palladium, and m is the hydrogen‐to‐palladium atom ratio.Keywords
