Hydroxide Ion Conducting Antimony(V)-Doped Tin Pyrophosphate Electrolyte for Intermediate-Temperature Alkaline Fuel Cells

Hydroxide Ion Conducting Antimony(V)-Doped Tin Pyrophosphate Electrolyte for Intermediate-Temperature Alkaline Fuel Cells

Ion conductor: A series of Sn1–xAxP2O7 (AV=V, Nb, Ta, and Sb) compounds was synthesized, among which Sn0.92Sb0.08P2O7 (see picture) showed the highest hydroxide ion conductivity in the temperature range of 50–200 °C (0.08 S cm−1 at 100 °C and 0.05 S cm−1 at 200 °C). This high conductivity was also c...

Description
Summary:Ion conductor: A series of Sn1–xAxP2O7 (AV=V, Nb, Ta, and Sb) compounds was synthesized, among which Sn0.92Sb0.08P2O7 (see picture) showed the highest hydroxide ion conductivity in the temperature range of 50–200 °C (0.08 S cm−1 at 100 °C and 0.05 S cm−1 at 200 °C). This high conductivity was also confirmed under fuel‐cell‐operating conditions.
