description

Kurināmā elementi izraisa lielu interesi, jo ļauj pārveidot degvielu (piemēram, ūdeņradi, metanolu, metānu) bez Karno cikla ierobežojumiem, sasniedzot augstu lietderības koeficientu. Polimēru elektrolīts ļauj izveidot kurināmā elementu, kas strādā pie pietiekami zemām temperatūrām, optimālām izmantošanai portatīvo enerģijas avotu un autotransporta jomās. Izstrādājot šo darbu, uz protonus vadošā polimēra (Nafions) bāzes sintezēti jauni paraugi, pievienojot polimēram oksīdus, kas ļauj uzlabot materiāla spējas vadīt protonus pie paaugstinātām temperatūrām un relatīvā mitruma zem 100%. Tika veikti sintezēto materiālu fizikālķīmisko īpašību pētījumi, tādi kā: termogravimetrijas analīze, impedances spektroskopija, materiālu ūdens absorbcija un absorbcijas kinētika, ar mērķi noteikt, kāds no izgatavotajiem materiāliem ir labāks kā elektrolīts kurināmā elementos.
