ABSTRACT: It is a technology that produces the hydrogen gases
by using only the microorganism and sunlight from the wastewater to be at a
loss because of processing. And, the produced hydrogen uses the fuel cell and
is used to generate electricity. Because
this technology doesn't use the organic matter that becomes food, and use the
organic matter included in waste, clean power generation is possible. We
researched the improvement of the hydrogen gas production efficiency. The
purple non-sulfur photosynthesis bacillus was purely cultured, the substrate
dependency was clarified, and the best substrate dosage was decided. Moreover,
it was shown that the light wave length conversion net was effective for the
hydrogen gas production efficiency improvement. On the other hand, a too strong
light intensity showed becoming the growth obstruction of phototropic bacteria.
When the light intensity for the photosynthesis is insufficient, the light wave
length conversion net can support this. On the other hand, there was an effect
of easing the trouble by light when the light intensity was excessive. We were
able to offer the design parameter to produce the hydrogen gases with the
wastewater efficiently.
