This report presents the results of work carried out at NPL between February 2010 and March 2011 to develop traceable methods for the measurement of trace levels impurities in hydrogen for fuel cell applications. Experimental results are presented and discussed, and the limits of detection of each method developed are assessed against those in International Standards. It should be noted that this report summarises NPL's suite of analysis methods as of the date of this report (August 2011); suggestions for further development of the work are also given.
