A study on the hydrogen generation's characteristics via non-thermal plasma and carrier gas

비열플라즈마에 의한 수소발생에 미치는 캐리어가스의 영향

This paper is investigated about the effect of carrier gas and humidity for generating hydrogen gas. In the experimental result of generating hydrogen gas by non-thermal plasma reactor, the rate of generating hydrogen gas is different with what kind of carrier gas is. We used two types of carrier gas, such as $N_2$ and He. $N_2$ as carrier gas is more efficient to generate hydrogen gas than He because $N_2$ is reacted with $O_2$, which is made from water dissociation. In comparison with no humidity and humidity 45[%], the generation of hydrogen gas is decreased with increasing the humidity. That is the result that the energy for water dissociation is reduced on water surface because a part of plasma energy is absorbed at the small particle produced from humidifier.
