摘要：

Some data in mixed-reactant fuel cells (MRFC) at Newcastle using formic acid, methanol and ethanol are reported. The importance of using a fuel-tolerant selective cathode catalyst has been identified. The influence of fuel and oxidant conditions and feeding patterns has been evaluated. The cell performance using air, oxygen and hydrogen peroxide is reported. The highest peak power density of 16 mW cm(-2) was obtained with formic acid. The MRFC gave power densities approximately half those of a conventional, un-mixed-reactant fuel cell. (C) 2008 Elsevier B.V. All rights reserved.
