Abstract
The design of direct methanol fuel cell based portable power source is being pursued at JPL. Performance data obtained on Nafion-based fuel cells have been used to develop a closed loop system model. The model has been exercised to obtain information on the impact of the various possible operating conditions on size, mass and efficiency of portable systems. Flow rate of air, methanol concentration and temperature are found to key controllable variables that significantly impact system size and efficiency. The results of the modeling studies are discussed.Keywords
