Sistem sočasne proizvodnje toplote in električne energije z visokotemperaturnimi gorivnimi celicami s protonsko prevodnimi membranami

Lotrič, Andrej (author), Sekavčnik, Mihael (mentor)

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 inovativen katalizator z veliko aktivnostjo za reakcijo MSR. Na osnovi eksperimentalnih podatkov, dobljenih z ločenimi meritvami karakteristik MSR in HT PEMFC sklada, smo izdelali inovativen hibridni numerični model za določitev masnih in energijskih tokov ter energijskega izkoristka integriranega sistema. Eksperimentalni in numerični rezultati potrjujejo izvedljivost avtotermnega energetskega sistema. Podane so smernice za izdelavo prototipa integriranega sistema.

Abstract

In the thesis, a concept of a small portable power unit with an integrated methanol steam reformer (MSR) and a high-temperature proton exchange membrane fuel cell (HT PEMFC) stack has been developed. A reactor was designed to use a highly active state-of-the-art MSR catalyst. Based on experimental data, gathered by measurements of individual characteristics of the MSR and the HT PEMFC stack, an innovative hybrid numerical model was developed which was used to calculate mass and energy flows and the efficiency of the integrated system. Experimental and numerical results confirm the feasibility of the autothermic energy system. Guidelines for the construction of the prototype integrated system are presented.
