scope:

This part of IEC 62282 defines the evaluation methods of typical performances for electric energy storage systems using hydrogen. This is applicable to the systems that use electrochemical reaction devices for both power charge and discharge. This document applies to systems that are designed and used for service and operation in stationary locations (indoor and outdoor). The conceptual configurations of the electric energy storage systems using hydrogen are shown in Figure 1 and Figure 2. Figure 1 shows the system independently equipped with an electrolyser module and a fuel cell module. Figure 2 shows the system equipped with a reversible cell module. There is an electrolyser module and a fuel cell module, or a reversible cell module, an overall management system (which includes a data interface and may include a pressure management), a thermal management system (which may include a heat/cold storage), a water management system (which may include a water storage) and a purge gas supply (inert gas, practically neither oxidising nor reducing) as indispensable components.
