Fuel Cell Technologies

IEC TS 62282-9-102:2021 provides a set of specific rules, requirements and guidelines (i.e. so-called product category rules (PCR) according to ISO 14025 and thus in line with ISO 14040 and ISO 14044) for characterizing the environmental performance of stationary fuel cell combined heat and power (CHP) systems, and alternative systems for residential applications based on life cycle thinking primarily for communication to consumers. This document covers stationary fuel cell CHP systems and alternative heat (and power) systems for residential applications that primarily serve heating purposes. The systems can be complemented with a hot water storage tank and one or more additional heat generators. The systems are connected to the electricity grid. The environmental performance is characterized in an EPD for each individual heat-related device or CHP generator separately. This document also describes how the environmental performance of a given combination of heat-related devices (including CHP generators) is characterized based on the environmental performance of its individual components. The domestic heat distribution system, district heating, or local infrastructures for fuel supply or for fuel storage are not considered.

IEC TS 62282-9-101:2020 provides a streamlined methodology to assess major environmental impacts of stationary fuel cell power systems for residential applications. The fuel cell power systems can be complemented with a supplementary heat generator and/or a thermal storage system such as a hot water tank. The analysis can include the import of electricity from the grid or the export to the grid. The analysed systems are intended to meet the electricity and heat demand of a given household. This document provides a set of specific rules, requirements and guidelines based on life cycle thinking for the description of relevant environmental impacts of fuel cell power systems that can be complemented with a supplementary heat generator or a thermal storage system. This document also provides guidance on how to communicate these environmental impacts to consumers.

IEC TS 62282-7-2:2014 provides for SOFC cell/stack assembly units, testing systems, instruments and measuring methods, and test methods to test the performance of SOFC cells and stacks. This technical specification is to be used for data exchanges in commercial transactions between cell/stack manufacturers and system developers or for acquiring data on a cell or stack in order to estimate the performance of a system based on it. Users of this technical specification may selectively execute test items suitable for their purposes from those described in this technical specification.

IEC TS 62282-7-1:2017(E) covers cell assemblies, test station setup, measuring instruments and measuring methods, performance test methods, and test reports for PEFC single cells. This document is used for evaluating: - the performance of membrane electrode assemblies (MEAs) for PEFCs in a single cell configuration; - materials or structures of PEFCs in a single cell configuration; or - the influence of impurities in fuel and/or in air on the fuel cell performance.

IEC/PAS 62282-6-150:2011(E) covers micro fuel cell power systems using hydrogen produced from the reaction of an aqueous solution with solid UN Division 4.3 (water-reactive) compounds in indirect PEM fuel cell systems that are wearable or easily carried by hand, providing d.c. outputs that do not exceed 60 V d.c. and power outputs that do not exceed 240 VA.

IEC 62282-8-201:2020 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 are an electrolyser, a hydrogen storage and a fuel cell, or a reversible cell, a hydrogen storage and an overall management system (which may include a pressure management) as indispensable components. There may be a battery, an oxygen storage, a heat management system (which may include a heat storage) and a water management system (which may include a water storage) as optional components. The performance measurement is executed in the area surrounded by the outside thick solid line square (system boundary)

IEC 62282-8-102:2019 deals with PEM cell/stack assembly units, testing systems, instruments and measuring methods, and test methods to test the performance of PEM cells and stacks in fuel cell mode, electrolysis and/or reversible mode.

IEC 62282-8-101:2020 addresses solid oxide cell (SOC) and stack assembly unit(s). It provides for testing systems, instruments and measuring methods to test the performance of SOC cell/stack assembly units for energy storage purposes. It assesses performance in fuel cell mode, in electrolysis mode and/or in reversible operation. This document is intended for data exchanges in commercial transactions between cell/stack manufacturers and system developers or for acquiring data on a cell or stack in order to estimate the performance of a system based on it. Users of this document may selectively execute test items suitable for their purposes from those described in this document. Users can also substitute selected test methods of this document with equivalent test methods of IEC TS 62282-7-2 for SOC operation in fuel cell mode only.

IEC 62282-6-400:2019 covers the interchangeability of power and data between micro fuel cell power systems and electronic devices to provide the micro fuel cell power system compatibility for a variety of electronic devices while maintaining the safety and performance of the micro fuel cell system. For that purpose, this document covers power interfaces and their connector configuration. The power management circuitry and power sharing methodology are also provided. This document also covers the data communication protocol and its data specification. Operation modes and alert conditions are also provided for the means to comply with the power control requirements of the electronic device.
