Fuel cartridge interchangeability
1 Scope
This International Standard covers interchangeability of micro fuel cell (MFC) fuel cartridges to provide the cartridge compatibility for a variety of MFC power units while maintaining the safety and performance of MFC power systems. For this purpose, the standard covers fuel cartridges and their connector designs. Fuel type, fuel concentration and fuel quality are also covered. This standard also provides for the means to avoid the miss-connection of an improper fuel cartridge. Test methods for verifying the compliance with the interchangeability requirements for fuel and fuel cartridges are also provided in this standard. IEC/PAS 62282-6-1 and IEC 62282-6-200 do not cover fuel cartridge or fuel from the cartridge. IEC 62282-6-300 describes the performance test methods of fuel cartridges, the fuel from the cartridge, and markings to realize the interchangeability of fuel cartridges. These include performance effect of fuel cartridges, such as fuel quality which may affect the performance of MFC power units and usable fuel volume from fuel cartridges.
A MFC power system block diagram is shown in Figure 1. MFC power systems and MFC power units are defined as those 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. This standard covers the fuel cartridge for MFC power units and the mechanical interface of connectors between fuel cartridges and MFC power units. The main body of this standard includes methanol liquid fuel cartridges, including methanol and water solution. Annex A shows the background used to determine the forces expected in normal operation and in foreseeable misuse. Annex B shows the example design for test fixtures for the fuel connector and fuel cartridge type tests.
NOTE Liquid fuel means fuel transported from a cartridge to a MFC power unit in the liquid state, and gas fuel means fuel transported from a cartridge to a power unit in the gaseous state.

c) Attempting to connect the cartridge to the MFC power unit with a force expected in normal operation or foreseeable misuse shall not result in leakage or fuel vapour loss, or otherwise result in subsequent leakage or fuel vapour loss if used properly in the future.
62282-6-300 © IEC:2009 – 15 – 4.1.2.3 If a force expected in normal operation or foreseeable misuse is applied to the cartridge and/or MFC power unit while the cartridge is connected to the MFC power unit, there shall be no leakage and no fuel vapour loss under the following conditions. a) If a cartridge is connected to a MFC power unit and loading is applied to the cartridge or MFC power unit, there shall be no leakage and no fuel vapour loss.
b) If the cartridge can be connected to the MFC power unit after unintentional loading, there shall be no leakage and no fuel vapour loss. If another cartridge cannot be connected to the MFC power unit, there shall be no leakage and no fuel vapour loss. 4.1.2.4 If a force expected in normal operation or foreseeable misuse is applied to the cartridge side connector and/or MFC power unit side connector while the cartridge is being removed from the MFC power unit, there shall be no leakage and no fuel vapour loss under the following conditions. a) Attempting to remove the cartridge from the MFC power unit with a force expected in normal use shall not result in leakage or fuel vapour loss or otherwise result in subsequent leakage or fuel vapour loss if used properly in the future.
b) Improper removal of the cartridge by the user from the MFC power unit shall not damage the cartridge side connector or MFC power unit side connector such that: when another cartridge is connected properly to the MFC power unit or when another MFC power unit is connected properly to the cartridge, there shall be no leakage and no fuel vapour loss. If the cartridge cannot be removed from the MFC power unit, there shall be no leakage and no fuel vapour loss. 4.1.2.5 If the cartridge side connector is damaged while the cartridge is being connected, used or removed by a force expected in foreseeable misuse, the following requirements shall be met. a) Leakage or fuel vapour loss shall not be detected even if the cartridge side fuel connector is damaged.
b) When the cartridge side connector is damaged at its coupling part, no leakage and no fuel vapour loss shall be caused if the MFC power unit side connector is connected, used, or removed. This is not intended to include any damage to the MFC power unit caused by a user with an obviously damaged cartridge.
c) If the cartridge side connector is damaged, it shall be easy for the user to remove the damaged cartridge and/or any broken parts of the cartridge from the MFC power unit side connector. The connection of a new cartridge to the MFC power unit shall not be affected.
d) The MFC power unit side connector shall not be damaged. The cartridge side connector shall be designed with suitable connector material so as to cause the MFC power unit side connector no damage. 4.2 Construction and actuation requirements
4.2.1 General Fuel connectors of cartridges and MFC power units shall comply with the compatibility requirements for construction and actuation as follows. The following requirements shall be applied to all types of cartridges such as insert, exterior, attached and satellite types. 4.2.2 Connector sealing
For MFC power unit side connectors, the connection cycling durability test for connect/disconnect (IEC/PAS 62282-6-1 requires 1 000 times) is required.
– 16 – 62282-6-300 © IEC:2009 4.2.3 Connector sequence
The indicated sequence shall be followed for connection of a cartridge with an MFC power unit: first, the sealing is secured between the cartridge side connector and the MFC power unit side connector; second, the MFC power unit valve is opened; and finally the cartridge valve is opened. When the cartridge side connector is removed, the cartridge valve is closed first, then the MFC power unit valve is closed, and finally the seal is opened.
4.2.4 Mechanical keys Connectors between the cartridge and the MFC power unit shall have a mechanical key structure which permits only the connection of the proper combination of fuel cartridges and MFC power units in order to prevent wrong connections in fuel and/or internal pressure of the cartridge. 4.2.5 Material requirement The connector material shall be chosen to maintain the integrity of connection and withstand methanol and aqueous methanol solution of pH 2,5. See 4.5 of IEC/PAS 62282-6-1 for material selection.
4.3 Interchangeable fuel connectors 4.3.1 General The compatibility of fuel connectors is achieved by standardizing the dimensions of the MFC power unit side connector. Subclauses 4.3.2.7 to 4.3.2.9, 4.3.3.8 to 4.3.3.10, 4.3.4.7 to
