Experimental Investigation of a Passive Direct Methanol Fuel Cell
Direct methanol fuel cells (DMFC) are getting increasing attention as a possible power source for application in the field of power electronics where the energy requirements are relatively small. The major advantage of the DMFC is their high energy density in comparison to the conventional batteries. In this study, the performance of a passive direct methanol fuel cell was investigated under fi...
متن کاملFunctionalized and Electrospun Polymeric Materials as High-Performance Membranes for Direct Methanol Fuel Cell: A Review
Proton exchange membranes (PEM) for a direct methanol fuel cell (DMFC) have main drawbacks which are methanol permeability, reduced proton conductivity and the cost of the membrane. This paper reviews different polymeric materials such as fluorinated, non-fluorinated, acid-base complex, and composite membranes for DMFC. Currently, nonfluorinated membranes gain a lot of atte...
متن کاملTransient investigation of passive alkaline membrane direct methanol fuel cell
Passive direct methanol fuel cell (DMFC) is considered as an attractive power source for portable devices. In this study, a transient multiphase model for passive alkaline anion exchange membrane DMFC (AAEMDMFC) is developed. The results show that the power density decreases during the operation and is more difficult to maintain stable with higher current density or lower voltage. The fuel effi...
متن کاملA Micro Direct Methanol Fuel Cell with Self-pumping of Liquid Fuel
This paper introduces a micro direct methanol fuel cell (μDMFC) with an imbedded self-pumping mechanism to deliver liquid fuel. The fuel is propelled without any power consuming component (e.g., a pump), while removing the CO2 bubbles generated by the fuel-cell electrochemical reaction of the system. Furthermore, the pumping rate is self-regulated by the reaction, i.e., by the load. By eliminat...
متن کاملDesign and Fabrication of a Silicon-based Micro Direct Methanol Fuel Cell Stack
This paper presents a silicon-based micro direct methanol fuel cell (μDMFC) stack with compact stacked structure and a unique shared anode plate. The μDMFC stack consists of two fuel cells in electrically parallel connection, while the fuel transport is arranged in series. Experimental results show that the μDMFC stack generates a power density of 12.71mW/cm, almost twice as much as that of a s...
