Eksperimentalna analiza delovanja PEM gorivne celice pri različnih konfiguracijah hlajenja

Kompara, Lara (author), Mori, Mitja (mentor)

V zaključnem delu je raziskan vpliv različnih konfiguracij zračnega hlajenja na delovanje PEM gorivne celice. Eksperimentalno je bilo preizkušenih šest konfiguracij, pri katerih smo spreminjali smer pretoka zraka ter moč ventilatorjev. Delovanje gorivne celice je bilo ovrednoteno z meritvami polarizacijskih krivulj in izračunom izhodne moči. Rezultati so pokazali, da večji in ustrezno usmerjen pretok zraka izboljša hlajenje ter omogoča stabilno delovanje pri višjih obremenitvah. Najboljše rezultate je dosegla konfiguracija z najvišjo močjo ventilatorjev in vpihovalnim načinom hlajenja.

• Title: Experimental analysis of PEM fuel cell performance under different cooling configurations

Abstract

This final thesis investigates the impact of different air-cooling configurations on the performance of a PEM fuel cell. Six configurations were tested experimentally, varying the direction of air flow and the power of the fans. Fuel cell performance was evaluated through measurements of polarization curves and calculating the output power. The results showed that a higher and properly directed air flow improves cooling and enables stable operation under higher loads. The best results were achieved with the configuration using the highest fan speed and with blowing air into the fuel stack.
