T/CES 176-2022 Testing and evaluation method for lifespan of stationary proton exchange membrane fuel cell stack

Scope

Scope: This document specifies the test and calculation methods for the service life of fixed proton exchange membrane fuel cell stacks. This document applies to proton exchange membrane fuel cell stacks used in fixed fuel cell power generation systems that are connected directly or via a conversion switch to the power grid, or to independent distribution systems. The proton exchange membrane fuel cell stacks tested have a rated output power of not less than 10kW and are used as the main power supply, secondary power supply, or backup power supply to evaluate the service life of fixed proton exchange membrane fuel cell stacks. Main technical content: The China Electrotechnical Society group standard T/CES 176-2022, "Evaluation Methods for the Service Life of Fixed Proton Exchange Membrane Fuel Cell Stacks", was proposed by the China Electrotechnical Society and drafted and compiled by units such as Wuhan University of Technology. This standard specifies the test conditions and test platforms for fixed proton exchange membrane fuel cell stacks, and sets technical requirements for fuel cell stack operation simulation testing methods, test steps, operation condition diagrams, instrumentation, and service life range evaluation. It provides standard guidance for verifying the effectiveness of proton exchange membrane fuel cell stack service life evaluation methods and fills the gap in standards for performance testing and evaluation of fixed proton exchange membrane fuel cell stacks.
