摘要：

This paper presents the electrochemical evaluation from polarization curves of a microfluidic fuel cell that uses formic acid as fuel and different oxidants (dissolved oxygen, air and hydrogen peroxide), concentrations of fuel and flow rates. The micro-device was constructed by UV-lithography technique and the electrocatalysts consisted in commercial Pd/XC-72 and Pt/C for anode and cathode respectively. The maximum power density achieved was 6.7 mW cm(-2) at 0.5 V using 0.5 M HCOOH and dissolved oxygen at 600 mu Lmin(-1). (C) 2013 Elsevier Ltd. All rights reserved.
