Papa Bipolar a me ke kelepona wahie hydrogen

ʻO ka hana opā bipolar(ʻike ʻia hoʻi he diaphragm) ʻo ia ke hāʻawi ʻana i ke kahawai kahe kinoea, pale i ka collusion ma waena o ka hydrogen a me ka oxygen i loko o ke keʻena kinoea pākahiko, a hoʻokumu i kahi ala o ke au ma waena o nā pou Yin a me Yang ma ke ʻano series. Ma ke kumu o ka mālama ʻana i kahi ikaika mechanical a me ke kūpaʻa kinoea maikaʻi, pono ka mānoanoa o ka papa bipolar e like me ka hiki ke hōʻemi i ke kūpaʻa conduction i ke au a me ka wela.

Nā mea kalapona. ʻO nā mea kalapona e komo pū me ka graphite, nā mea kalapona i hoʻoheheʻe ʻia a me ka graphite i hoʻonui ʻia (flexible). Hoʻohana ka papa bipolar kuʻuna i ka graphite mānoanoa a ua mīkini ʻia i loko o ke kahawai kinoea · Loaʻa i ka papa bipolar graphite nā waiwai kemika paʻa a me ke kūpaʻa pili haʻahaʻa me ka mea.

Pono nā papa bipolar i ka mālama ʻili kūponoMa hope o ke kau ʻana o ka nickel ma ka ʻaoʻao anode o ka papa bipolar, maikaʻi ke alakaʻi ʻana, a ʻaʻole maʻalahi ka pulu ʻia e ka electrolyte, hiki ke pale i ka nalowale o ka electrolyte. ʻO ka pilina maʻalahi ma waena o ka diaphragm electrolyte a me ka papa bipolar ma waho o ka wahi kūpono o ka electrode hiki ke pale pono i ke kinoea mai ka leaka ʻana i waho, ʻo ia ka mea i kapa ʻia ʻo "wet seal". I mea e hōʻemi ai i ka pala o ka carbonate i hoʻoheheʻe ʻia ma ke kila kila ma ke kūlana "wet seal", pono e "aluminized" ka mōlina papa bipolar no ka pale ʻana.

ʻO kekahi o nā ʻāpana nui o ke kelepona wahie hydrogen ʻo ia nā papa electrode wahie graphite. I ka makahiki 2015, ua komo ʻo VET i ka ʻoihana kelepona wahie me kona mau pono o ka hana ʻana i nā papa electrode wahie graphite. Ua hoʻokumu ʻia ka hui ʻo Miami Advanced Material Technology Co., LTD.

Ma hope o nā makahiki o ka noiʻi a me ka hoʻomohala ʻana, ua loaʻa i nā kauka holoholona ka ʻenehana kūpono no ka hana ʻana10w-6000w Nā pūnaewele wahie hydrogenKe hoʻomohala ʻia nei ma luna o 10000w mau hunaola wahie i hoʻoikaika ʻia e ke kaʻa e kōkua i ke kumu o ka mālama ʻana i ka ikehu a me ka palekana o ke kaiapuni. No ka pilikia nui o ka mālama ʻana i ka ikehu hou, ke hōʻike nei mākou i ka manaʻo e hoʻololi ka PEM i ka ikehu uila i hydrogen no ka mālama ʻana a hoʻopuka ka hunaola wahie hydrogen i ka uila me ka hydrogen. Hiki ke hoʻopili ʻia me ka hana mana photovoltaic a me ka hana hydropower.
