... methanol fuel cell liquid–vapor two-phase model pore size distribution CO 2 flow water management methanol crossover fuel cells The mass transfer of carbon dioxide within a direct methanol fuel cell (DMFC) is critical to regulate the mass transfer of fuel (methanol) and water [ 1 – 3...

...Liangfei Xu; Chuan Fang; Junming Hu; Siliang Cheng; Jianqiu Li; Minggao Ouyang; Werner Lehnert Water management is critical for the operation of a polymer electrolyte membrane fuel cell (PEMFC). For the purposes of high power and long working-lifetime of PEMFCs, external humidifiers are always...

...Scott Lux; Lifeng Gu; Grant Kopec; Robert Bernas; George Miley This study evaluated water management strategies to lengthen the run time of a batch fueled direct sodium borohydride/peroxide ( NaBH 4 / H 2 O 2 ) proton exchange membrane fuel cell. The term “batch fueled” refers specifically...

... interdigitated flow configuration facilitates mass transfer from the view of two-phase water management. The snapshots of the flow regime for pressure drops of 6000 Pa and 8000 Pa are given in Figs. 11a 11b , respectively. In addition, it is easily observed that the speed of water removal remarkably increases...

...Yong-Song Chen; Huei Peng Water management in a fuel cell is essential to ensure cell performance and life. In this study, a special single cell was designed for the purpose of detecting liquid water and water vapor simultaneously. The major difference between our design and traditional flow field...

...Kui Jiao; Biao Zhou Liquid water transport inside proton exchange membrane (PEM) fuel cells is one of the key challenges for water management in a PEM fuel cell. Investigation of the air-water flow patterns inside fuel cell gas flow channels with gas diffusion layer (GDL) would provide valuable...
