1 Scope This part of GB/T 20046 specifies the terms and definitions of test method for bipolar plate properties of proton exchange membrane fuel cell, the gas tightness test, flexural strength test, density test, resistance test, corrosion current density test, etc. for bipolar plate materials as well as the gas tightness test, resistance drop test, area utilization test, thickness uniformity test, flatness test, weight test, resistance test, etc. for bipolar plate components. This part is applicable to bipolar plate materials and components for various proton exchange membrane fuel cells. This standard is mainly divided into two parts: test for bipolar plate material properties and test for bipolar plate component properties. 2 Normative references The following documents are indispensable for the application of this document.
