Abstract

A study on the feeding effect on liquid-feed direct methanol fuel cells (DMFC) was carried out using the combined discrete dynamic simulation technique. A one-dimensional, two-phase rigorous dynamic model for a single-cell liquid-feed DMFC was developed and simulated dynamically. Feeding methods had an effect on the dynamic behavior of the system and the dynamic response of the system changed according to the feed flow rate and the feed concentration of methanol. The feeding effect on liquid-feed DMFC system could be fully understood to reduce undesired phenomena such methanol crossover. The feed flow rate and concentration of methanol played a key role in the operation of the DMFC system. The model was rigorous to describe the dynamics of the DMFC system and express the feeding strategy that contains discrete events making the simulation more difficult to reach the convergence. This is an abstract of a paper presented at the 2006 AIChE Annual Meeting (San Francisco, CA 11/12-17/2006).
