Scope

This Part of GB/T 33983 specifies the test items and test methods in terms of power
generation performance and environmental adaptability for direct methanol fuel cell
systems, classifies the direct methanol fuel cell systems with different power grades
into Grade I and Grade II, see Table 1, and distinguishes the test items they need.
Table 1 -- Classification of direct methanol fuel cell power generation systems
Battery type Rated power P Power grade
Micro direct methanol fuel cell
power generation system P ≤ 240 W Grade I
Mobile direct methanol fuel cell
power generation system 240 W< P ≤ 1000 W Grade II
The power generation performance and environmental adaptability test items and test
methods specified in this Part include.
a) Power generation performance under specified operating conditions. e.g. output
voltage, output power, start time, fuel consumption, etc.;
b) Power generation performance under special operating conditions. e.g. power
generation after deactivation, etc.;
c) Environmental adaptability under specified conditions. e.g. high temperature, low
temperature, high humidity, low humidity, drop, vibration etc.
This Part applies to direct methanol fuel cell systems with methanol or methanol
aqueous solution as fuel and with rated power not exceeding 1000 W.
The performance test method for direct methanol fuel cell systems with a rated power
greater than 1000 W may refer to this Part.
A typical direct methanol fuel cell system boundary diagram is shown in Figure 1.
