Measurements of hydrogen solubility and electrical resistance of some palladium-rhodium alloys by a gas phase technique

摘要

The hydrogen solubility and the corresponding change in electrical resistance of Pd-5 and 10 at. Rh alloys have been investigated by a gas phase technique. It was observed that low pressure hydrogen soluabilities decreased with increasing Rh content, whereas, the increment of main plateau pressures showed opposite behavior. The α _(max) and β_(min) Higher hydrogen solubility was attained for higher Rh content alloy. It seemed that pressure hysteresis was increased with increasing Rh content but practically it does not, because the loss in useful available energy for the 10 at. Rh-H system showed lower values than that for the 5 at. Rh-H system.
