چکیده انگلیسی
We have verified the effectiveness of ionomer as a carrier of oxygen to improve cold start-up of proton exchange membrane fuel cells. Galvanostatic cold start was performed on proton exchange membrane fuel cells to evaluate the effect of ionomer content in the catalyst layer on the durability of power generation at −30 °C. Cell voltage and internal resistance were measured, and polarization analysis was conducted to evaluate the cell voltage reduction. Cold start-up durability improved significantly with higher ionomer content in the catalyst layer because of higher oxygen permeation of ice formed in the catalyst layer. These results enable robust design of membrane electrode assemblies for cold start-up.
