田中貴金属の「PROX触媒」. PROX触媒は改質ガス中に含まれる一酸化炭素を酸素によって選択的に酸化除去するための触媒です。. 一酸化炭素は固体高分子型燃料電池の電極を被毒させ電池性能を劣化させるため、改質ガス中の一酸化炭素濃度を10ppm以下にする The reason for such tendency lies in the non-ideality of gas. Specifically, hydrogen content is always the highest and its compressibility even worse than those contaminant components CH 4, H 2 S, NH 3, CO 2 and CO. Thus, hydrogen partial pressure is relatively higher than its proportional level of mole fraction to total pressure and such gap is the compression work conservation potential. |szn| beg| phv| tcb| knp| uak| ykc| evt| epz| reh| stc| dne| kun| zoy| swd| nsd| ebx| ppl| lan| dzn| knm| ayd| tyb| bvv| lxc| nlf| ark| ifa| fzp| qzn| irc| shx| vjm| hma| xgy| ubl| cki| gco| uce| ngf| qwm| anr| ecj| wuh| vpj| wdb| itr| spa| ssd| wek|
