ʻO ka hoʻohana nui ʻana o ka rhodium ma ke ʻano he anti-wear coating a me ka catalyst no nā mea hana ʻepekema kiʻekiʻe, a hoʻohana ʻia ka rhodium-platinum alloy e hana i nā thermocouple.Hoʻohana ʻia ia no ka hoʻopaʻa ʻana ma luna o nā mea hoʻomālamalama kukui kaʻa, nā kelepona kelepona, nā ʻōlelo aʻoaʻo peni, etc. ʻO ka ʻoihana kaʻa ka mea hoʻohana nui loa i ka rhodium.I kēia manawa, ʻo ka hoʻohana nui ʻana o ka rhodium i ka hana kaʻa kaʻa kaʻa exhaust catalyst.ʻO nā ʻāpana ʻoihana ʻē aʻe e ʻai ana i ka rhodium ʻo ia ka hana aniani, ka hana ʻana o nā niho, a me nā huahana mea nani.Me ka hoʻomau mau ʻana o ka ʻenehana cell cell a me ka ulu ʻana o ka ʻenehana kaʻa wahie, e hoʻomau ka nui o ka rhodium i hoʻohana ʻia i ka ʻoihana kaʻa.

Loaʻa iā Proton exchange membrane fuel cell nā pono o ka zero emissions, kiʻekiʻe ka ikaika o ka ikehu, a me ka mana hiki ke hoʻololi.Manaʻo ʻia ʻo ia ke kumu mana hoʻokele kūpono no nā kaʻa uila i ka wā e hiki mai ana.Eia naʻe, pono ka ʻenehana i kēia manawa i ka hoʻohana ʻana i ka nui o nā nanocatalysts metala platinum makamae e mālama i kāna hana kūpono.
Ua hoʻomohala kekahi poʻe noiʻi i kahi hoʻololi proton membrane fuel cell cathode catalyst me ka hana catalytic maikaʻi loa a me ka paʻa, me ka hoʻohana ʻana i ka platinum nickel rhodium nano xian
ʻO ka platinum nickel rhodium ternary metal nanowire catalysts hou i hoʻomaikaʻi maikaʻi ʻia ma ke ʻano o ka hana maikaʻi a me ka paʻa catalytic, e hōʻike ana i ka hana maikaʻi loa a me ka hiki ke noi.
