GB/T 28816-2020Fuel cell--Terminology (English PDF)

Foreword

This Standard was drafted as per the rules specified in GB/T 1.1-2009.

This Standard replaced GB/T 28816-2012 Fuel Cell - Terminology; Compared with GB/T 28816-2012, this Standard has the major technical changes as follows.

--- Modify partial terms and definitions (see 3.1, 3.24, 3.33.1, 3.69.2, 3.85.1, 3.90, 3.104, 3.108.1, 3.108.4, 3.112.4, 3.115.5 of this Edition);

--- Add partial terms and definitions (see 3.20, 3.43.1, 3.58, 3.86.2, 3.110.4 of this Edition);

--- Delete the terms and definitions of "heat production rate" and "standby mode" (see 3.6.1 and 3.110.4 of 2012 Edition).

This Standard uses translation method to equivalently adopt IEC/TS 62282-1:2013 Fuel Cell Technologies - Part 1: Terminology.

This Standard made the following editorial modifications.

--- Modify the standard name into "Fuel Cell - Terminologies";

--- Move the abbreviations behind the corresponding English terms;

--- Modify partial terms and definitions (see 3.85, 3.106 of this Edition).

1 Scope
