Compact bipolar plate-free direct methanol fuel cell stacks

摘要

Fuel cells with a PtAu/C anode and a Pr-doped Mn_2O_3/C cathode were stacked without using a bipolar plate, and their discharge properties were investigated in a methanol aqueous solution bubbled with air. A three-cell stack exhibited a stack voltage of 2330 mV and a power output of 21 mW.
