Vpliv koncentracije oksidanta na katodi na delovanje nizkotemperaturne gorivne celice : magistrsko delo magistrskega študijskega programa II. stopnje StrojništvoKreuzer, ŽigaV magistrskem delu smo preučevali delovanje nizkotemperaturne gorivne celice s protonsko izmenjalno membrano. Glavni cilj naloge je bil eksperimentalno ovrednotiti učinek povečanja koncentracije ... oksidanta na katodi ter pogojev delovanja (temperatura, tlak) na karakteristiko delovanja gorivne celice. Rezultate, pridobljene na eksperimentalni merilni progi, smo ekstrapolirali na sklad gorivnih celic, ki bi bil uporabljen za pogon akrobatskega letala, ki obratuje v dveh režimih. V času akrobacij je za delovanje letala potrebna moč 300 kW, v preostalem času pa za let zadostuje moč 100 kW. Postavili smo numerični model delovanja sklada gorivnih celic, ki obratuje nad tlakom okolice in s koncentracijo kisika 100 %, ter enak sklad modelirali pri tlaku okolice in s koncentracijo kisika v zraku 21 %. S tem pristopom smo lahko primerjali delovanje sklada pri različnih pogojih. Rezultat numeričnega modela za izbrano misijo leta akrobatskega letala je sklad gorivnih celic, ki je večji in močnejši od skladov gorivnih celic, ki so trenutno na voljo na trgu. Za integracijo sklada gorivnih celic zahtevane moči v letalo smo predstavili več pristopov, kako izvesti modularno integracijo večih skladov manjših moči.Type of material - master's thesis ; adult, seriousPublication and manufacture - Ljubljana : [Ž.
