Single passive direct methanol fuel cell supplied with pure methanol

▶ A new single passive DMFC supplied with pure methanol using a PM to control the methanol transport is designed and tested. ▶ The maximum power density of about 21 mW cm−2 is obtained with the PM size of 9 cm2. ▶ Compared with the DMFC supplied with 3 M methanol solution, the energy density provided by this new DMFC has increased about 6 times.
