“…The water produced at the cathode catalysis layer is normally collected in the diffusion layer and discharged through the channel. If not discharged in time, the water will block the cathode channel, hinder the mass transfer of oxygen, and affect the PEMFC performance [29]. With the channel depth of 1mm, the effects of channel and rib widths on the performance of the radial flow field was analyzed based on the water content distribution in the cathode channel of Radial-I, Radial-II and Radial-III.…”

The channel structure of flow field is an important influencing factor of the operation and performance of proton exchange membrane fuel cell (PEMFC). Based on circular bipolar plate, three radial flow fields, namely, Radial-I, Radial-II and Radial-III, with different structures were created, and compared to disclose the effects of radial channel on the flow field for the PEMFC. The results show that radial flow fields clearly outperformed traditional flow fields like parallel, single serpentine and multiple serpentine flow fields. Radial-II has the highest current density and power density than any other flow field. The channel and rib widths of radial flow field have greater impacts on PEMFC performance than channel depth. Radial flow field can effectively improve the water discharge and reduce the pressure drop of the PEMFC. The research findings shed new light on the performance improvement of the PEMFC.

“…Then the current densities decreased quickly again at the time of rapidly remove of liquid water drops. According to former studies [Bozorgnezhad, Shams, Kanani et al (2015); Liu and Pan (2012); Banerjee and Kandlikar (2014)], transparent material was adopted for end plates of PEMFC to observe the inner flow characteristics. Cathode side was chosen for observation and analysis as liquid water mainly existed on cathode side.…”

Water management in proton exchange membrane fuel cells (PEMFC) is a topic of great importance for the optimization of these systems. Effective proton conductivity calls for moderate moisture content in the membrane, while uneven water distribution can lead to instability of the whole flow field, thereby decreasing the performance of the fuel cell. In the present study, a simplified two-tier hybrid structure is used to investigate the impact of the dynamic behavior of liquid water on the current density of the PEMFC. Simulation results show that water droplets attached to wall sides tend to increase current density. Visualization experiments confirm the existence of liquid droplets and the enhancement of current density, while indicating that the best performance and stability of fuel cell are attained for a cathode air flow rate of 300 ml/min.

International audienceIn this paper, a Fault Tolerant Control Strategy (FTCS) dedicated to PEMFC (Polymer Electrolyte Membrane Fuel Cell) water management is implemented and validated online on a real PEMFC system. Thanks to coupling a Fault Detection and Isolation (FDI), an adjustable controller and a reconfiguration mechanism, FTCS allows addressing the important challenge of Fuel Cell (FC) reliability improvement. Only few works have already been conducted on FTCS applied to FC actuators faults, and none of them on FC water management faults. In this work, a neural-based diagnosis tool is computed online as FDI component and is coupled to a self-tuning PID controller. This diagnosis tool shows low computational time and high detection performance. The self-tuning PID controller shows robustness against noise measurements and model uncertainties. Its low computational cost makes it a suitable control method for real-time FTCS. Performed on a PEMFC system, the FTCS shows promising results on fault diagnosis and performance recovery
