Fibrous and tubular structures for PEMFC catalyst supports combining electrospinning, heat treatments and atomic layer deposition (ALD)
Abstract
The general requirements for fuel cell catalyst supportmaterials are high electronic conductivity; high specificsurface area and high electrochemical and chemicalstability. Material structure should also enable good gasand water vapor transport in it. Currently typicalstructures for PEM fuel cell catalysts consists Ptnano-particles on carbon black support. We as suggestinga new concept where supports consist of (nano)fibrouscarbon and ceramic (nano)tubular structures providinghigh surface area for catalyst reaction and high porosityfor good management the product water. Materials arecorrosion resistant and electrically conductive.Fibrous and tubular material structures are based onelectrospinning - method leading to submicron ornanoscale fibre diameters. Our approach to producecore-shell carbon-ceramic catalyst supports includespreparation of electrospun precursor fibres,stabilization and carbonization of precursor fibres intocarbon, and atomic layer deposition (ALD) coating methodto produce conducting niobium doped titanium oxide layeronto carbon fibres. Our approach to produce tubularcatalyst supports includes preparation of sacrificialelectrospun template fibres, preparation of oxide layeron fibres by ALD and removal of polymer template from thestructure by heat treatment. Oxide coating and tubestructures produced by ALD are annealed to formconductive surface suitable for Pt deposition by ALD.Heat treatment processes of web samples were carried outusing tubular furnace suitable for roll-to-rolloperation.In this presentation we will report production of suchfibrous and tubular materials, optimization work done forimproving support quality, and Pt coating of suchstructures, as well as discuss of use of these mateialsin catalyst applications.
