Introduction

Energy storage systems using reversible mode can effectively utilize excess electric energy and promote power regulation and renewable energy utilization.

GB/T 42847 focuses on the performance of energy storage systems based on electrochemical modules (a combination of fuel cells and electrolytic cells, or reversible fuel cells). Ability to test methods.

GB/T 42847 aims to establish performance testing methods for energy storage systems based on reversible mode fuel cell modules. It is planned to be composed of the following departments Composition.

---Part 1: Reversible mode solid oxide cell and stack performance test methods. The purpose is to give the solid oxide single cell and Test systems, instruments and measurement methods and tests for performance testing of stacks in fuel cell mode, electrolysis and/or reversible mode method.

---Part 2: Reversible mode proton exchange membrane single cell and stack performance testing methods. The purpose is to give the proton exchange membrane single cell and Test systems, instruments and measurement methods and tests for performance testing of stacks in fuel cell mode, electrolysis and/or reversible mode method.

---Part 3: Electrical energy storage system performance test methods. The purpose is to give performance tests of hydrogen-based electrical energy storage systems method.

1 Scope

This document specifies typical performance evaluation methods for hydrogen-based electrical energy storage systems.

This document is applicable to devices with electrolysis and power generation functions electrochemical reaction device.

This document applies to systems designed, applied and operated for fixed (indoor and outdoor) scenarios.

The conceptual configuration of a hydrogen-based electric energy storage system is shown in Figures 1 and 2. Figure 1 is independently equipped with an electrolytic cell module and a system with a fuel cell module; Figure 2 shows a system equipped with a reversible battery module. Its essential components include electrolytic cells, hydrogen storage, fuel battery, or reversible battery, oxygen storage and integrated management system (which may include pressure management). Its optional components include batteries, oxygen storage, thermal management system (can include heat storage) and water management system (can include water tank). Its performance test is in the thick solid line square (system boundary) in the figure performed outside the scope.

Note: In this document, the term "reversible" does not refer to the thermodynamic sense of an ideal process. In the field of fuel cells, it is usually divided into fuel cell mode and electrolysis mode. Battery operating modes that alternate between modes are called "reversible".
