Ua manaʻo ʻo PEM electrolytic cell platinum-coated titanium no ka wai electrolysis gas diffusion layer

ʻO ka Titanium fiber felt series kahi ʻano o ka titanium fiber sintered feel me ka porosity kiʻekiʻe a me ka nui gradient pore. ʻO kāna kaʻina hana he uea titanium ma o kahi kaʻina hana kūikawā e hana ai i ka micron fiber, titanium fiber ma hope o ka waiho ʻana, sintering, i loko o nā mea porous, kona ʻano ʻokoʻa ʻekolu-dimensional fiber network a me ka hoʻopili piha ʻana i ka pore e loaʻa iā ia kahi ʻano o nā hana kūikawā. I nā noi hana hydrogen, ua manaʻo ʻia ka titanium i nā waiwai electrolytic maikaʻi loa, ʻo ke anawaena pore kūpono loa, ʻoi aku ka maikaʻi o ka ea permeability a me ka porosity ma lalo o nā kūlana o ke kaomi ea 6CTC. Hōʻike ka ʻikepili hoʻāʻo i ka hoʻohālikelike ʻia me ka pepa kalapona a me ka pauka titanium sheet, ʻo ka titanium manaʻo ka liʻiliʻi loa o ka overpotential i hoʻokumu ʻia e ka liʻiliʻi ohmic resistance, no laila e hōʻemi ana i ka hoʻohana ʻana i ka ikehu a hoʻomaikaʻi i ka hana electrolytic. Eia kekahi, ʻoi aku ka haʻahaʻa o ka volta ma mua o ka pepa kalapona a me ka pauka titanium sheet, e hōʻike ana i ka manaʻo o ka titanium i ʻoi aku ka maikaʻi o ka hana electrolytic, a ʻo ka titanium manaʻo he porosity kiʻekiʻe a me ka nui o ka pore nui, kahi kūpono i ka hoʻokuʻu ʻana i ke kinoea.
