Thermoelectric Power Hydrogen Sensors for Reversible Hydrogen Storage Materials

Thermoelectric power has demonstrated a capability for rapid hydrogen assessment and can achieve the equivalent of the pressure-composition-temperature (activity) diagram. Effective use of hydrogen storage materials occurs in the alpha+beta two-phase region of the activity diagram. A thorough assessment of the content of each phase in this two-phase region can optimize the performance of hydrogen storage materials. The use of thermoelectric power measurements as a hydrogen sensor for reversible batteries is discussed.
