MT 203 - TC 105/MT 203

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.
