摘要：
A new single passive direct methanol fuel cell (DMFC) supplied with pure methanol is designed, assembled and tested using a pervaporation membrane (PM) to control the methanol transport. The effect of the PM size on the fuel cell performances and the constant current discharge of the fuel cell with one-fueling are studied. The results show that the fuel cell with PM 9 cm(2) can yield a maximum power density of about 21 mW cm(-2), and a stable performances at a discharge current of 100 mA can last about 45h. Compared with DMFC supplied with 3 M methanol solution, the energy density provided by this new DMFC has increased about 6 times. (C) 2010 Elsevier B.V. All rights reserved.
