My‭ ‬actual‭ ‬research field is situated in the‭ ‬bioelectrochemical engineering and more particularly in the biological production of hydrogen,‭ ‬an energetic vector used as principal combustible in fuel cell.
The studied bio-processes produce hydrogen by process from organic‭ acids ‬found either in industrial effluents or issued from a previous dark biofermentation process or by chemical transformation of biomasses‭‬.‭
The studied biological organism‭ ‬principally‭ ‬concerns the non pathogenous anaerobic photosynthetic bacterium,‭ ‬Rhodobacter capsulatus‭ ‬in reason of various advantages‭ ‬(light spectra use of 68.5%‭) ‬degradation of‭ ‬great range of carbonated substrates‭ (‬lactate,‭ ‬acetate,‭ ‬.....‭)‬,‭ ‬one of the greater productivity‭ (‬130‭ ‬ml H2/h/g bacterial dry weight in batch culture and‭ ‬320‭ ‬ml H2/h/g bacterial dry weight in‭ ‬continuous culture‭)‬.
Under photosynthetic conditions,‭ ‬the produced hydrogen purity reached‭ ‬85-95%,‭ ‬with a substrate conversion of‭ ‬50-95%.‭ ‬The hydrogen can be directly converted,‭ ‬without a purification step,‭ ‬in electricity inside a fuel cell‭ (‬PEMFC or SOFC‭ ‬noted B see above)‬.

Indirect Biofuel Cell associating H2 photobioproduction (R. capsulaltus, A) and Solid Oxide Fuel Cell (noted B).l

Different carbon substrates can be used by‭ ‬Rhodobacter capsulatus:‭ ‬cheese industry waste,‭ ‬potato industry,‭ ‬cane sugar industry,‭ ‬....‭ ‬and all type of industry which products carbonated waste rich either in lactate,‭ ‬acetate,‭ ‬....compounds.
The methodology of DOE‭ (‬design of experiments‭) ‬is regularly and successfully applied‭ ‬in the laboratory using‭ ‬the‭ ‬two photosynthetic‭ ‬lab-made chambers‭ (‬45‭ ‬experiments‭ ‬tested‭ ‬in parallel‭) ‬or during international collaborations‭ (‬ethylen bioproduction,‭ ‬H2 bioproduction from whey ....)‬.
