✦ Synopsis

The direct methanol type system consists of simple and compact equipment, and is suited for automobile use. However this system possesses low power density and its internal resistance needs to be reduced. This research investigated characteristics of power output and thermal efficiency in a proton-exchange-membrane fuel cell directly fuelled with methanol solution. Some influences of catalyst amount and separator groove design on power output were also found.

In a direct methanol fuel cell (DMFC) with a Na"on membrane, a methanol solution fed to the anode permeates to the cathode. This phenomenon causes the depolarization loss at the cathode and the DMFC performance grows worse. In this research, by continuously measuring the concentration of CH OH, CO a

The present work consists of a tubular-shaped direct methanol fuel cell (DMFC) that is operated completely passively with methanol solution stored in a central fuel reservoir. The benefit of a tubularshaped DMFC over a planar-shaped DMFC is the higher instantaneous volumetric power energy density (p
