Cold-start icing characteristics of proton-exchange membrane fuel cells

Investigation of the Ice Melting Process in a Simplified Gas Diffusion Layer of Fuel Cell by the Lattice Boltzmann Method

“…In addition, the formation of ice could also be judged by measuring impedance. Li et al experimentally measured the voltage, impedance, and GDL temperature during the cold start process. The effects of starting temperature, current density, and surface hydrophobicity of the microporous layer on cold start performance and freezing characteristics were investigated.…”

Effects of Endplate Assembly on Cold Start Performance of Proton Exchange Membrane Fuel Cell Stacks

“…[9,10] A great number of experimental studies have been conducted to investigate the cold start performance and characteristics of PEMFCs. The focus has been placed on the visualization of ice formation, [11][12][13] optimization of loading strategy, [14] and analysis of starting-up conditions, [15][16][17] flow-field design, [18,19] and tailoring of fuel cell materials. [20][21][22][23][24][25] Cold start models have also been developed for single cells and stacks to gain a better understanding of the start-up process.…”

Improvement of cold start performance of polymer electrolyte fuel cell using microporous and gas diffusion layers with patterned wettability

“…MPLs can provide good contact for the interface between the CL and GDL, as well as limit the accumulation of liquid water on the surface of the CL, thus improving the performance of the fuel cell. 16 Li et al 17 believed that improving the hydrophobicity of the MPL could optimize the cold start performance of a fuel cell. However, Yang et al 18 suggested that, compared with the hydrophobicity of the MPL, reducing the thickness of the proton exchange membrane is more conducive to the cold start of PEFCs because a thinner membrane is more beneficial for reducing the ohmic polarization of the fuel cell and improving the hydration degree of the membrane.…”
