Porous membranes based on polybenzimidazole (PBI) are firstly introduced in direct borohydride fuel cell application (DBFC). Membranes with different thicknesses and porosity are successfully fabricated via water vapor phase inversion process. The prepared membranes show excellent ion conductivity and chemical stability under DBFC operating condition. Compare with Nafion 115, the prepared membranes...
Ethanol–water mixtures were converted directly into H 2 with 67.6% yield and >98% conversion by catalytic steam reforming at 350°C over modified Ni/Y 2 O 3 catalysts heat treated at 500°C. XRD was used to test the structure and calculate the grain sizes of the samples with different scan rates. The initial reaction kinetics of ethanol over modified and unmodified Ni/Y ...
