Fuel cell technologies - Part 3-202: Stationary fuel cell power systems - Performance test methods for small fuel cell power systems for multiple units operation

IEC 62282-3-202:2025 provides performance test methods specialized for the thermal and electrical characteristics of an energy management system to effectively share the heat and power of networked small stationary fuel cell power systems. These test methods are applied for each small stationary fuel cell power system. This document covers small stationary fuel cell power systems which can be complemented with a supplementary heat generator or a thermal storage system, or both, such as:

- output: rated electric power output of less than 10 kW for each system;

- output mode: grid-connected or independent operation or stand-alone operation with alternating current (AC) output not exceeding 240 V or direct current (DC) output;

- operating pressure: maximum allowable working pressure of less than 0,1 MPa (G) for the fuel and oxidant passages;

- fuel: gaseous fuel (natural gas, liquefied petroleum gas, propane, butane, hydrogen) or liquid fuel (kerosene, methanol); oxidant: air.

This document does not apply to small stationary fuel cell power systems with electricity storage other than (small scale) back-up power for safety, monitoring and control.
