Summary:Expressions are given for the tritium distribution between gas and liquid phases arising from prolonged electrolysis of D 2O on Pd electrodes saturated with absorbed deuterium. Errors associated with commonly employed experimental procedures and their interpretation using a simple model for the distribution between the gas and liquid phases are evaluated. With regard to tritium production, an unambiguous resolution requires a complete mass balance. Conclusions based on partial data, such as the measurement of the tritium content in a single cell component (e.g. electrode, electrolyte or “electrolytic” gas phase), may be misleading, particularly if production rates are either low or intermittent.
