Fuel Cell - Terminology

1 Scope
This standard provides uniform terminology in the forms of diagrams, definitions and equations related to fuel cell technologies.

It is applicable to include but not limited to stationary power, transportation, portable power and micro power applications.

Not found here are words and phrases, which can be found in standard dictionaries, engineering references or the IEC 60050 series.

Note: The first edition of IEC 62282 was intended as a resource for the working groups and users of the IEC 62282 series of fuel cell standards. This third edition, as well as the second edition, has been expanded into a general fuel cell glossary.

2.2 Definition of diagram functions

The overall design of the power systems anticipated by this standard is formed by an assembly of integrated systems, as necessary, intended to perform designated functions, as follows:

— Automatic control system: System that is composed of sensors, actuators, valves, switches and logic components that maintain the fuel cell power system (3.49) parameters within the manufacturer’s specified limits without manual intervention.

— Fuel cell module: Equipment assembly of one or more fuel cell stacks (3.50) which electrochemically converts chemical energy to electric energy and thermal energy intended to be integrated into a vehicle or power generation system.

— Fuel cell stack: Equipment assembly of cells, separators, cooling plates, manifolds (3.70) and a supporting structure that electrochemically converts, typically, hydrogen rich gas and air reactants to DC power, heat and other reaction products.

— Fuel processing system: System of chemical and/or physical processing equipment plus associated heat exchangers and controls required to prepare, and if necessary, pressurize, the fuel for utilization within a fuel cell power system (3.49).

— Onboard energy storage: System of internal electric energy storage devices intended to aid or complement the fuel cell module (3.48) in providing power to internal or external loads.

— Oxidant processing system: System that meters, conditions, processes and may pressurize the incoming supply of oxidant for use within the fuel cell power system (3.49).

— Power conditioning system: Equipment that is used to adapt the electrical energy produced by the fuel cell stack(s) (3.50) to application requirements as specified by the manufacturer.
