Abstract
A method of forming a fuel cell catalyst system, the method includes providing an anticorrosive, conductive catalyst support material having oxygen vacancies and a formula (I): MgTi2O5-δ (I), where δ is any number between 0 and 3 optionally including a fractional part denoting the oxygen vacancies, coating the catalyst support material with a polymeric film, attaching a catalyst material onto the polymeric film, removing the polymeric film, and providing additional material onto the support material to increase physical, electrical, and/or mechanical contact between the catalyst material and the catalyst support material.

A method of forming a fuel cell catalyst system, the method comprising:
- providing an anticorrosive, conductive catalyst support material having oxygen vacancies and a formula (I):
- MgTi2O5-δ (I),
- where
- δ is any number between 0 and 3 optionally including a fractional part denoting the oxygen vacancies;
- coating the catalyst support material with a polymeric film;
- attaching a catalyst material onto the polymeric film;
- removing the polymeric film;
- and
- providing additional material onto the support material to increase physical, electrical, and/or mechanical contact between the catalyst material and the catalyst support material.
A method of forming a fuel cell catalyst system, the method comprising:
- synthesizing catalyst support nanoparticles including an anticorrosive, conductive material having oxygen vacancies and a formula (I):
- MgTi2O5-δ (I),
- where
- δ is any number between 0 and 3 optionally including a fractional part denoting the oxygen vacancies;
- forming a polymeric layer around each of the nanoparticles;
- subsequently attaching a plurality of catalyst nanoparticles onto the polymeric layer such that at least some of the catalyst nanoparticles are in contact with the catalyst support nanoparticles;
- and
- removing the polymeric layer.
