“…Actually, it is preferable to select galvanostatic (controlled current) mode when a quantitative analysis directly linked to cell current should be performed. However, the maximum limited current density cannot be easily evaluated in the case of this transparent cell [11]. For safe and reliable cell operation during the visualization experiment, the constant voltage mode was adopted in this study.…”

“…inside the PEM fuel cells. Also, the water management is highly linked to thermal management because a small change in temperature can change the saturation pressures, mole fractions in the mixture, species diffusivity, and species conductivity [9][10][11]. The water inside the PEM fuel cells can be evaporated, condensed, and removed in spite of even a small variation in temperature.…”

“…Especially, as the cell temperature increases without proper control, it can trigger the membrane dehydration and lower the performance and finally cause serious damages to the fuel cell. Therefore, the comprehensive understanding of the temperature distribution inside the PEM fuel cell is imperative to novel water and thermal management [11][12][13][14][15]. Various experimental techniques including invasive and non-invasive methods have been applied for the temperature measurements within PEM fuel cells.…”

“…Various experimental techniques including invasive and non-invasive methods have been applied for the temperature measurements within PEM fuel cells. First of all, thermocouples and microthermocouples with the help of micro-electro-mechanicalsystems (MEMS) based technologies have been commonly used for the temperature measurements at different locations inside PEM fuel cells [11,[15][16][17]. Infra-red thermal imaging techniques [18] are frequently used with the advantages of providing temperature distribution of the whole surface.…”

Water management is considered to be one of the main issues to be addressed for the performance improvement of proton exchange membrane (PEM) fuel cells. In this paper, to investigate cathode flooding and its relationship with temperature distribution, an experimental study was carried out on cathode sides of an operating single PEM fuel cell. For the direct visualization of temperature fields and water transport in cathode flow channels, a transparent cell was designed and manufactured using quartz window. Liquid water transport and distribution in the flow channels were investigated experimentally. Also, the visualization of temperature distributions in the cathode channels was made by using an IR (infra-red) camera. Results indicate that the temperature rise near the exit of cathode flow channels was found. It is expected that this study can effectively contribute to get the detailed data on water transport linked with thermal management during the operation of a PEM fuel cell.

Use of Segmented Cell Operated in Hydrogen Recirculation Mode to Detect Water Accumulation in PEMFC

et al. 2013

Adequate water management is crucial to increase stability and durability of Polymer Electrolyte Membrane Fuel Cells. In this paper, a test rig suitable for water balance and nitrogen crossover studies was built around a hydrogen‐air segmented cell and used to indirectly assess flooding or drying conditions in specific zones of the active cell area. In particular, the anode of the segmented cell was operated in recirculation mode with continuous water removal. Current density distribution (CDD) diagrams were obtained for different anode operating parameters, namely, the recirculated gas flow rate, anode pressure, and time between purges. Water accumulation at the electrodes was assessed from CDD diagrams and confirmed using water balance and flow‐patterns calculations. It was concluded that lower recirculation flow rates led to flooding due to decreased water removal capabilities at the anode. For higher recirculation flow rates, drying was observed in one zone of the cell but homogeneous CDD in the other. Finally, the use of partially segment bipolar plates was proposed to increase the in‐plane electrical resistance between adjacent segments. The partial segmentation increased the segment to segment in‐plane electrical resistance between 14 and 21% and decreased the through‐plane to in‐plane resistance ratio by 17%.

The knowledge of heat loss from the fuel cell will be helpful to decide on material components and fixture design. In the present study, a new methodology is proposed to estimate heat loss from passive DMFC using interferometry technique. Printed circuit board (PCB) fixture is adapted in our study that replaces end plate and current collector. The accurate cell temperature distribution is useful to estimate the heat from the cell fixture. The cell temperature distribution is measured based on infra‐red (IR) thermography and this temperature distribution is used to estimate the heat transfer coefficient of the fuel cell. Differential interferometer (DI) technique is used to estimate the heat transfer under different operating conditions of the fuel cell. The cell surface temperature measured on the cathode gas diffusion layer (GDL) is 42 °C for 5M methanol concentration whereas for 1M, it is 32 °C. Based on the analysis , the average heat transfer coefficient of the cell at vertical PCB rib orientation using 5M methanol concentration is estimated to be 2.7 Wm−2 K−1. A two‐dimensional non‐isothermal single‐phase half‐cell (cathode) model is developed and compared with experiments. The cell temperature distribution obtained from model is in good agreement with experiments. The model is extended to study the effect of PCB orientation and thermal conductivity of PCB material on heat loss. The cell at vertical PCB rib orientation retains 15 ‐ 20% more heat than horizontal rib. Therefore, the cell temperature showed 42 °C and performed 10% better compared to horizontal PCB rib.
