V doktorskem delu smo razvili koncept prototipa majhnega, močnostnega, prenosnega sistema, v katerem sta integrirana parni reformer metanola (MSR) in sklad visokotemperaturnih gorivnih celic s protonsko prevodnimi membranami (HT PEMFC). Razvili in izdelali smo reaktor, v katerem je bil uporabljen in ...

We have investigated the concept of an integrated system for small, manportable power units. The focus of this study is the direct thermal coupling of a methanol steam reformer (MSR) and a high-temperature proton exchange membrane fuel cell (HT PEMFC) stack. A recently developed low-temperature (LT) ...
