Description / Abstract:
Scope of Test Procedures
This recommended practice is intended to provide a framework for
performance testing of fuel cell systems (FCS's) designed for
automotive applications with direct current (DC) output. The
procedures described allow for measurement of performance relative
to claims by manufactures of such systems with regard to the
following performance criteria.
—Power
—Efficiency
—Transient Response
—Start and Stop Performance
—Physical Description
—Environmental Limits
—Operational Requirements
—Integration
Since this recommended practice is based on the principal of
performance measurement relative to a claim, the testing practices
should take care to include any qualifying or unique circumstances
leading to the test results reported in order to achieve full
disclosure. For example, efficiency as defined in section 3.1.9
allows for the inclusion of thermal output benefit. If a test
result is reported which takes advantage of this allowance this
stipulation should be noted with the efficiency figure and the
useful purpose of the thermal output (e.g. cabin heating) should be
made clear.
