Study of mineralization by electrochem oxidation of org compd contained in aq effl: phenol and carboxylic acids stemming from its ox (maleic, oxalic, formic). The performance of BDD is compared with that of PbO2 (commercial). The phenol oxidation (aq slt) shows that BDD has better kinetic and energetic properties. Kinetic studies (MA in the presence of OA and/or FA) shows that OA is directly oxidized whereas MA and FA react with electrogenerated OH°. The presence of ClO4- leads oxygen transfer on MA more important than a pure faradaic process, assuming ox of ClO4- into ClO4°. Oxidation of oil in water emulsion (metallurgy industry effl) gives rise to a full mineralization of surfactant (sodium dodecylbenzenesulfonate) and org phase (lauryl alc, lauric or oleic ac) without demixtion. The numeric resolution of a physico-chemical model shows that the oxidation of the org molecules by OH° occurs in a reaction layer, the thickness of which is about 1000 times as fine as the diffusion layer

Defects known to shorten the lifetime of polymer electrolyte membrane fuel cells (PEMFC) can appear on different membrane electrode assembly (MEA) components and under different forms due to manufacturing processes or operational aging of the fuel cell. This work concerns the occurrence, detection, and propagation of defects in PEMFC MEA, and more specifically at the anode. To this end, an accelerated stress test (AST) combining potential and humidity cycles -induced by load variations-, and open-circuit hold is applied to standard MEA, and to MEA with initial defects. Those customized MEA were intentionally prepared with a lack of active layer at the anode, the defect being located either near the hydrogen inlet or near the hydrogen outlet. Periodic electrochemical characterizations were carried out using a segmented instrumented linear cell, allowing to monitor the cell performance through the currents, electrode potentials, and local impedance, as well as the evolution of the electrochemical active surface (ECSA) at the anode and cathode during the ageing test, with a spatial resolution along the channels. An electrochemical impedance spectroscopy study was conducted jointly, using equivalent electrical circuits, and focusing on the detection of the anodic contribution to the global impedance of the cell. Results showed an accelerated degradation of the MEA and the first evidence of defect propagation, in terms of loss of ECSA at the anode. This propagation occurred in the direction of the hydrogen flow. The ECSA at the cathode also appeared to be impacted, although apparently homogeneously. Significant membrane thinning was also observed in the defective segments, with probable propagation to adjacent segments, but over a longer time period
