AbstractA marine green alga, Platymonas subcordiformis can produce hydrogen under the regulation of a proton uncoupler CCCP. In this study, alkaline hydrogen-oxide fuel cell (AFC) was directly used to deplete hydrogen to maintain a low partial pressure of hydrogen in the reactor once it was produced from the algae in the photobioreactor. The hydrogen evolution in this AFC integrated process was characterized and compared with that of the process without AFC. The results show that the duration of hydrogen evolution was prolonged significantly and the yield of H2 was improved about 2.3 times. Higher level of hydrogen in the reactor can inhibit the hydrogen evolution from the algal cells. It is critical to sustain the activities of hydrogenase and the photosynthetic system II (PSII) of the algae for further improving H2 production from P. subcordiformis.
