Hydrogen production by Spirulina maxima 2342 under different light intensities and quantification employing a fuel cell

In this work the photosynthetic hydrogen production employing Spirulina maxima 2342 microorganisms was determined under different experimental conditions, for the same biomass property (concentration) and three different light intensities (150, 112 and 75 µE/m2.s). The hydrogen production was quantified employing a proton exchange membrane fuel cell (PEMFC) which produces electricity using the hydrogen produced in this experiment. The highest faradaic efficiency and hydrogen flow rate into the PEMFC (1.54 × 10-8 kg/h) was obtained for a light intensity of 150 µE/m2.s.
