Oxide-supported PtCo alloy catalyst for intermediate temperature polymer electrolyte fuel cells

- Good performance is obtained for PtCo alloy/Ta-doped Ti-oxide for ORR in PEMFCs.
- High electrochemical stability is shown by PtCo/Ta-doped Ti-oxide at 1.4 V RHE.
- Oxide support shows promoting effect for ORR at intermediate temperatures (110 °C).
- Higher performance is achieved with Pt-Co/oxide vs. Pt/oxide in PEMFCs.
