title = "System modeling and simulations of active direct methanol fuel cell (DMFC) systems under various ambient temperatures and operating conditions",
abstract = "Direct methanol fuel cells (DMFCs) are potential candidates for portable backup power generation and auxiliary power unit (APU) due to their advantageous features such as the ease of storage and delivery. Optimizing each components of DMFC system is critical to improve overall system performance and power density. We develop a DMFC system model in which major system components including fuel and water tanks, liquidgas separator, heat exchangers, pumps and blowers are considered with a DMFC stack. The model is implemented within a commercial flow-sheet simulator, ASPEN HYSYS and then applied to a DMFC system to investigate the effects of DMFC operating parameters and heat management. Special emphasis is placed on establishing an active control strategies of DMFC stack temperature and methanol crossover rate via optimizing system components and operating conditions. This study contributes to identifying innovative active DMFC system designs and configuration.",
