Experimental conditions such as humidier water quality, repeatable and
accurate humidity streams, cell xture design and cell assembly, and other
external conditions can affect the performance of the cell and the validity and
quality of the research data. For highly analytical testing, it is very impor-
tant to consider and control all parameters of the testing setup. For example,
when using electronic load, the closer the load rating is to the expected per-
formance of the cell or stack under test, the more accurate the results will be.
Mass ow control and humidication systems may also be subject to unac-
ceptable accuracy errors ...
