A fuel cell oxidation reduction reaction catalyst comprising:
- a carbon powder substrate;
- an amorphous conductive metal oxide intermediate layer on the substrate;
- and
- a plurality of chained electrocatalyst particle strands bound to the layer to form an interconnected network film thereon having a thickness of up to 10 atom monolayers.
A fuel cell oxidation reduction reaction catalyst comprising:
- a carbon powder substrate;
- and
- a plurality of chained electrocatalyst particle strands bound to the carbon powder substrate to form an interconnected network film thereon having a thickness of up to 10 atom monolayers.
A method of producing a fuel cell oxidation reduction reaction catalyst comprising:
- within a vacuum chamber,
- mixing a carbon powder substrate in a side-oriented rotating fluidization drum such that the substrate repeatedly travels toward a top of the drum and then falls to a bottom of the drum;
- and
- vacuum depositing electrocatalyst particles onto the falling substrate to form chained electrocatalyst particle strands bound to the substrate.
A method of producing a fuel cell oxidation reduction reaction catalyst comprising:
- within a vacuum chamber,
- delivering a carbon powder substrate on a conveyor such that the substrate repeatedly travels toward a top of the conveyor and then falls to a bottom of the conveyor, and
- vacuum depositing electrocatalyst particles onto the falling substrate to form chained electrocatalyst particle strands bound to the substrate.
