摘要：
Shortening start-up time of vehicle proton exchange membrane (hydrogen) fuel cells in cold environment is one of urgent problems to be solved. In this study, based on heat transfer data analysis and COMSOL finite element software, two different sizes of 30 kW hydrogen fuel cell stacks in constant temperature system were comparatively investigated. Meanwhile, a strategy for low temperature storage and cold start of vehicle proton exchange membrane fuel cells were proposed. The results indicate that the fuel cell stack with a smaller aspect ratio required less energy for preserve constant temperature under -30 ℃. The hydrogen fuel cell stack can be maintained above 0 ℃ for 13 h by providing 33.93 kg pure paraffin phase enthalpy or consuming 1.15 L pure methanol fuel to provide 6 786 kJ energy. This study provides an approach to solve the problems of low temperature storage and cold start of vehicle hydrogen fuel cells. © 2022 Zhejiang University. All rights reserved.
