Iipleyiti zeBipolar

Iipleyiti zeBipolarzenziwe ngegraphite okanye isinyithi; basasaza ngokulinganayo amafutha kunyei-oxidant kwiiseli ze-fuel cell. Bakwaqokelela umsinga wombane owenziweyo kwiitheminali zokuphuma.

Kwi-cell-cell fuel cell, akukho bipolar plate; nangona kunjalo, kukho ipleyiti enecala elinye elibonelelaukuhamba kwee-electron. Kwiiseli zepetroli ezineseli engaphezulu kwesinye, kukho ubuncinci i-bipolar plate (ulawulo lokuhamba lukhona kumacala omabini epleyiti). Iipleyiti zeBipolar zibonelela ngemisebenzi emininzi kwiseli yamafutha.

Eminye yale misebenzi ibandakanya ukuhanjiswa kwamafutha kunye ne-oxidant ngaphakathi kweeseli, ukwahlula iiseli ezahlukeneyo, ukuqokelelwa kweeseli.umsinga wombaneeveliswayo, ukukhutshwa kwamanzi kwiseli nganye, ukufumisa iigesi kunye nokupholisa kweeseli. Iipleyiti ze-bipolar nazo zineendlela ezivumela ukuhamba kwee-reactants (i-fuel kunye ne-oxidant) kwicala ngalinye. Ziyakhai-anode kunye ne-cathode compartmentskumacala ahlukeneyo epleyiti ye-bipolar. Uyilo lwemijelo yokuhamba lunokwahluka; zisenokuba ngumgca, zibhijene, zingqamane, zibe yikama okanye zibe nezithuba ezilinganayo njengoko kubonisiwe kwifoto engezantsi.

Iindidi ezahlukeneyo ze-bipolar plate [COL 08]. a) Imijelo edityanisiweyo yokuqukuqela; b) imijelo yeekhoyili ezininzi; c) imijelo yokuhambahamba ehambelanayo; d) Imijelo yokuqukuqela ephakathi

Izinto eziphathekayo zikhethwa ngokusekelweukuhambelana kweekhemikhali, ukumelana nomhlwa, ixabiso,conductivity yombane, isakhono sokusasazwa kwegesi, ukungakwazi ukunyamezela, ukukhululeka komatshini, amandla omatshini kunye nokuhanjiswa kwe-thermal.
