As the energy source of hydrogen fuel cells, the purity and impurity content of hydrogen greatly affect the battery's lifespan, efficiency, and safety performance. Accurately measuring the purity and impurity content of fuel hydrogen is extremely important. To this end, the principles, adaptability, advantages and disadvantages, and research progress of various analysis methods for 14 types of impurities, including water, total hydrocarbons, oxygen, helium, nitrogen, argon, carbon monoxide, carbon dioxide, total sulfur, formaldehyde, formic acid, ammonia, total halides, and particulate matter, involved in the current standards for fuel hydrogen products for proton exchange membrane fuel cell vehicles were elaborated, and a comparative analysis was conducted.
To accurately, quickly, and synchronously detect various gas impurities in hydrogen and achieve efficient evaluation of hydrogen quality. Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. uses pulse discharge helium ionization detector (PDHID) gas chromatography to determine ammonia qi in hydrogen. By examining the peak conditions of different chromatographic fillers, suitable chromatographic columns and conditions were selected and determined. The relative standard deviation of method repeatability is less than 2%, and the detection limit is less than 10 × 10-9 v/v, which can meet the determination of trace ammonia in hydrogen used in hydrogen fuel cells
