Pambuka kanggo energi hidrogen lan sel bahan bakar

Sel bahan bakar bisa dipérang dadimembran pertukaran proton sel bahan bakar (PEMFC) lan sel bahan bakar metanol langsung miturut sifat elektrolit lan bahan bakar sing digunakake

(DMFC), sel bahan bakar asam fosfat (PAFC), sel bahan bakar karbonat molten (MCFC), sel bahan bakar oksida padat (SOFC), sel bahan bakar alkali (AFC), lan liya-liyane. Contone, sel bahan bakar membran pertukaran proton (PEMFC) utamane gumantung ingmembran pertukaran proton medium transfer proton, sel bahan bakar alkalin (AFC) nggunakake elektrolit basis banyu alkalin kayata solusi kalium hidroksida minangka medium transfer proton, lan sapiturute, miturut suhu kerja, sel bahan bakar bisa dipérang dadi sel bahan bakar suhu dhuwur lan suhu kurang. sel bahan bakar, mantan utamane kalebu sel bahan bakar oksida padat (SOFC) lan sel bahan bakar karbonat molten (MCFC), sing terakhir kalebu sel bahan bakar membran pertukaran proton (PEMFC), sel bahan bakar metanol langsung (DMFC), sel bahan bakar alkalin (AFC), sel bahan bakar asam fosfat (PAFC), dll.

Membran pertukaran proton fuel cells (PEMFC) use water-based acidic polymer membranes as their electrolytes. PEMFC cells must operate under pure hydrogen gas due to their low operating temperatures (below 100 ° C) and the use of noble metal electrodes (platinum based electrodes). Compared with other fuel cells, PEMFC has the advantages of low operating temperature, fast start-up speed, high power density, non-corrosive electrolyte and long service life. Thus, it has become the mainstream technology currently applied to fuel cell vehicles, but also partially applied to portable and stationary devices. According to E4 Tech, PEMFC fuel cell shipments are expected to reach 44,100 units in 2019, accounting for 62% of the global share; The estimated installed capacity reaches 934.2MW, accounting for 83% of the global proportion.

Sel bahan bakar nggunakake reaksi elektrokimia kanggo ngowahi energi kimia saka bahan bakar (hidrogen) ing anoda lan oksidan (oksigen) ing katoda dadi listrik kanggo nyopir kabeh kendaraan. Secara khusus, komponen inti sel bahan bakar kalebu sistem mesin, sumber daya tambahan lan motor; Antarane wong-wong mau, sistem engine utamané kalebu engine dumadi saka reaktor listrik, sistem panyimpenan hidrogen kendaraan, cooling sistem lan DCDC voltase converter. Reaktor minangka komponen paling kritis. Iki minangka papan reaksi hidrogen lan oksigen. Iki dumadi saka pirang-pirang sel tunggal sing ditumpuk bebarengan, lan bahan utama kalebu piring bipolar, elektroda membran, piring pungkasan lan liya-liyane.
