Abstract:Protoninvaihtopolttokenno (PEMFC) on polttokennotyyppi, joka toimii matalassa lämpötilassa ja käyttää polttoaineena vetykaasua. PEMFC:tä pidetään lupaavana teholähteenä moneen sovellukseen, mm. tieliikenteeseen, laivoihin, varavoimasovelluksiin ja sähköverkon vakautukseen. Kaupallisia tuotteita on jo saatavilla. Tärkeimmät PEMFC:iden yleistymistä rajoittavat tekijät ovat kattavan vetyjakeluverkoston puuttuminen sekä PEMFC:iden hinta ja kestävyys. |
