Présence de FEMTO-ST sur la foire de Hanovre

L'équipe Systèmes hybrides et Pile à combustible (SHPAC) du département Energie de FEMTO-ST, membre de la fédération de recherche CNRS FCLAB, sera présente à la foire d'Hanovre du 7 au 11 avril prochain pour présenter les résultats du projet européen D-CODE: DC/DC Converter-based Diagnostics for PEM Systems (Collaborative Project FCH-JU-2009).

Le projet D- CODE vise à développer la spectroscopie en ligne d'impédance électrochimique (EIS) et les algorithmes de diagnostic associés afin de disposer d'informations directes sur l'état du système. L'EIS a été prouvé être un outil efficace de diagnostic pour les tests de laboratoire. Il sera mis en œuvre grâce à un nouveau convertisseur DC/DC intelligent conçu par les partenaires du projet. Des algorithmes de diagnostic dédiés en ligne sont développés selon différentes approches pour contrôler efficacement les défauts ou les mécanismes de dégradation. Deux types de piles à combustible PEM (pile à membrane échangeuse de protons) sont considérés pour des alimentations de secours (PEM basse température) et de la microcogénération (PEM haute température). Des tests approfondis sont effectués pour valider les stratégies de diagnostic et évaluer leur efficacité. L'objectif est d'améliorer les conditions opératoire du système afin d'augmenter la durée de vie. Les algorithmes développés au sein de SHPAC, dans le cadre de la fédération de recherche FCLAB, sont basés sur des approches du type logique floue et réseaux de neurones avancés, en collaboration avec le département OPTIQUE de FEMTO-ST. L'outil développé peut facilement être étendu à d'autres applications de systèmes de piles à combustible PEM et, en perspective, à toutes les technologies de piles à combustible.
