“…So a PEMFC with the channels downwards performances better than that with channels under other directions. These results match those in both experimental and computational works [4,12,15,19].…”

“…Liquid water clearly appears in the channels of the cathode side (vertical channels) in form of water slugs, whereas no liquid water is present in the channels of the anode side (horizontal channels). A detailed analysis of the liquid water accumulation patterns, including a quantitative analysis of the water content within channels, was presented elsewhere 30.…”

A commercial 50 cm2 PEM (polymer electrolyte membrane) fuel cell was operated at 2.0 bara and 60 °C with two different oxidant gases, namely air and oxygen. A 3 × 3 matrix of anode and cathode reactants relative humidity (RHa and RHc) was used for a detailed characterization of the cell behavior. The cell performance and operating data including cell voltage and resistance were measured, and neutron radiographs were recorded during the entire operation to analyze the liquid water distributions within the cell. A quantitative analysis of the results is presented in this work, comparing the cell operation for both gases. The gain in cell voltage observed for the operation with O2, and the differences in the cell resistance and cell water content are quantitatively analyzed and discussed. Despite the differences in cell voltage, when the total volumetric cathode gas flow is maintained for air and oxygen feed, no significant differences are observed in the cell water content and water distribution.

“…This paper includes a quite complete survey of works dealing with water management issues, flooding phenomena and accumulation of water. Similar work has been done to characterize water accumulation on multiple serpentines channels of a 50 cm 2 PEMFC, using neutron imaging and statistical analysis [27]. The authors of [28] present a concept of PEM fuel cell with internal air flow humidification using the produced water.…”

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
