Electricity Generation by PEMFC Based on Rhodopseudomonas SP.
Proton exchange membrane fuel cell (PEMFC) needs pure hydrogen gas to generate direct current electricity.
PEMFC gives zero pollution emission unlike combustion power generation technology using fossil fuels. Biological hydrogen
(BioH2) production processes by purple nonsulfur photosynthetic bacteria (PNSB) is an alternative to generate hydrogen gas
with several benefits such as environmental friendly, economical and sustainable especially when bacteria obtained from
natural resources were growth. At present, many efforts on yields and efficient processes of photosynthetic bacteria have been
intensively studied worldwide. Little study is interested on electricity production by fuel cell supplied BioH2. In this work, the
electricity generation estimation for a PEMFC supplied by hydrogen produced by Rhodopseudomonas sp. was reported and
the mathematic equations were presented using numerical method. Voltage, current and power of PEMFC data were obtained
according to resistance loads. Power estimation is useful for small PEMFC study and application of biological hydrogen
produced by purple nonsulfur bacteria in future work.
