Test method about the influence of gaseous contaminants in reaction gas on the performance of proton exchange membrane fuel cells―Part 2:Gaseous contaminants in hydrogen
Test method about the influence of gaseous contaminants in reaction gas on the performance of proton exchange membrane fuel cells—Part 2: Gaseous contaminants in hydrogen
1 Scope
This standard specifies relevant terms and definitions, requirements of test platform and instruments, preparation before testing, test method and test report for the test method about the influence of gaseous contaminants in hydrogen, e.g. carbon monoxide (CO), on the performance of proton exchange membrane fuel cells.
This standard is applicable to proton exchange membrane fuel cell unit (hereinafter referred to as "fuel cell").
The volume fraction of gaseous contaminants in hydrogen gas to which the test method described in this standard is applicable is not less than 1 μL/L.
