Investigation of the Effect of CO2 bubbles and Slugs on the Performance of a DMFC by Means of Laser-optical Flow Measurements

Novel Flow Field with Superhydrophobic Gas Channels Prepared by One-step Solvent-induced Crystallization for Micro Direct Methanol Fuel Cell

“…The appearance and evolution of CO 2 bubbles can be quantitatively investigated using micro particle-imagevelocimetry (lPIV) technique, as have been reported by Burgmann and coworkers [7,8]. They found that the cell performance decay is closely related to the formation cycles of bubble slugs.…”

Investigating design parameter effects on the methanol flux in the passive storage of a direct methanol fuel cell

“…The information from CFD modeling and simulation helped them to increase the performance and better design of the flow field. In other case, Wong et al [14] and Burgmann et al [15] investigated the effect of flow field and CO 2 transportation on DMFC performance through the experimental way. They found that serpentine flow field shows higher voltage at higher current densities and better CO 2 transportation compared to parallel flow field.…”

Performance investigation of Passive Direct Methanol Fuel Cell in different structural configurations

“…Bewer et al (2004) investigated the nonuniform distribution of methanol upon the GDL due to the CO 2 bubbles generation in the anode channels and its influence on the power of a 600 cm 2 DMFC. Yang et al (2005) have studied the different two-phase flow regime established in the anode channels varying current density and cell orientation; Burgmann et al (2012) used a mPIV (Particle Image Velocimetry) to study the movement of the bubbles in the two phase flow, looking for solutions that might decrease their effects.…”
