A class of non-precious metal composite catalysts for fuel cells

Article Abstract:

A new class of low cost (non-precious metal)/(heteroatomic polymer) nanocomposite catalysts for the polymer electrolyte fuel cell (PEFC) cathode, which is capable of combining high oxygen-reduction activity with good performance durability, is presented. The results have shown that heteroatomic polymers could be used not only to stabilize the non-precious metal in the acidic environment of the PEFC cathode but also to generate active sites for oxygen reduction reaction.

A high-performance cathode for the next generation of solid-oxide fuel cells

Article Abstract:

Ba(0.5)Sr(0.5)-Co(0.8)Fe(0.2)O3-delta(BSCF) is presented as a new cathode material for reduced temperature solid-oxide fuel cells(SOFC) operation. The BSCF is ideally suited to 'single-chamber' fuel-cell operation, where anode and cathode reactions take place within the same physical chamber.

A thermally self-sustained micro solid-oxide fuel-cell stack with high power density

Article Abstract:

A thermally self-sustaining micro-SOFC stack with high power output and rapid start-up is demonstrated by using single chamber operation on propane fuel. The catalytic oxidation reactions are found to supply sufficient thermal energy to maintain the fuel cells at 500-600 degree Celsius.
