Resumo
A catalyst based on lanthanum chromite with exsolved metallic
ruthenium nanoparticles (LaCrO3-Ru) was applied as a catalytic
layer for internal ethanol steam reforming of anode-supported and
metal-supported solid oxide fuel cells. The metal support exhibits
limited catalytic properties for the ethanol steam reforming reaction.
Thus, the LaCrO3-Ru catalysts were optimized for operating
temperatures in the 600-700 °C range to promote stable ethanol
reforming. The catalytic layer had no significant impact on the
electrochemical properties of the fuel cell, and samples with and
without the catalytic layer exhibited similar performance in
hydrogen. Initial durability tests with LaCrO3-Ru layer have shown
that the catalytic layer plays a crucial role in the stability of the
metal-supported fuel cell under ethanol.
