Abstract

Electric conductivity of phosphate compounds with nitrogen was measured in order to use the materials for cogeneration type of fuel cell system, because the compounds have possibility to use as a new solid electrolyte. We used melamine orthophosphate (MOP), melamine pyrophosphate(MDP) and melamine polyphosphate(MPP) as melamine phosphates, and ammonium polyphosphate forms I (APP I ), II (APP II) and V (APP V ) as ammonium polyphosphates. The conductivity of the materials was measured by impedance analyzer. The conductivity of MDP with mixture ratio of diammonium hydrogen phosphate : melamine=1:1 and prepared at 200°C was 6× 10^-4S/cm and was the highest value at 200°C
