IEC 62282-3-201:2025 PDF

IEC 62282-3-201:2025 provides test methods for the electrical, thermal, and environmental performance of small stationary fuel cell power systems that meet the following criteria: - output: rated electric power output of less than 10 kW; - output mode: grid-connected/independent operation or stand-alone operation with single-phase AC output or 3-phase AC output not exceeding 1 000 V, or DC output not exceeding 1 500 V; - operating pressure: maximum allowable working pressure of 0,1 MPa (gauge) for the fuel and oxidant passages; - fuel: gaseous fuel (natural gas, liquefied petroleum gas, propane, butane, hydrogen, etc.) or liquid fuel (kerosene, methanol, etc.); - oxidant: air. This document describes type tests and their test methods only. No routine tests are required or identified, and no performance targets are set in this document. This document provides test methods to be carried out under laboratory conditions. This document covers fuel cell power systems whose primary purpose is the production of electric power and whose secondary purpose can be the utilization of heat. Accordingly, fuel cell power systems for which the use of heat is primary, and the use of electric power is secondary are outside the scope of this document. This third edition cancels and replaces the second edition published in 2017 and Amendment 1:2022. This edition includes the following significant technical changes with respect to the previous edition: - revision of Introduction; - revision of terms and definitions; - revision of Table 1; - revision of Figure 1, Figure 2, Figure 3 and Figure 4; - revision of measurement instruments (10.2); - revision of minimum required measurement systematic uncertainty (10.4); - revision of test conditions (Clause 11); - revision of operating process (Clause 12); - revision of fuel consumption test (14.2); - revision of heat recovery test (14.4); - revision of Figure 13 and Figure 14; - revision of calculation of results (14.14.4); - revision of Annex A and Annex B.
