products: FUEL-CELL AIR-MANAGEMENT SYSTEM-prototype(AMS)

A fuel cell requires a constant supply of clean air to be delivered at pressure in order to function effectively.  However, current Air Management Systems (AMS) typically suffers from unreliability, inefficiency, noise, and lack of durability with frequent and costly maintenance schedules. In most cases, the airflow cannot be tuned
to the operating characteristics of the fuel cell, causing further inefficiencies.

A cost effective and highly efficient air management system is a key enabler for fuel cell systems in electric power generation. TurboClaw® has been specifically designed to overcome the above limitations and is uniquely suited for this application.  Dynamic Boosting Systems Ltd is developing the AMS for PEM fuel cells and can presently offer prototype units for system integration and evaluation. Uniquely, it can be operated using speed and mass flow control.

In 2009, DBS was awarded a TSB-funded project (REF: BH004K) to develop an AMS based on TurboClaw® technology for use in a fuel cell system for off-grid telecommunication applications.

DBS fuel air management system is a superior product because of the following reasons:

• Low Cost: the price meets the targets for automotive industry. The AMS system includes the compressor, motor, drive, and supervisory control allowing either speed or flow-control.

• Durability: the compressor is mounted off the motor bearings and life, has been estimated in excess of 10,000 operational hours for an oil free system. Non-corrosive and passivated materials have been chosen for the AMS construction.


• Added Functionality: The AMS offers a number of advanced control options over and above the standard, conventional, speed control when a set of pressure and volume flow conditions are demanded by setting motor speed. These include mass-flow, pressure, and volume control.
