Using LT-PEM fuel cell systems for autarkic power or energy supply of remote sites is currently under discussion. The main advantages are higher lifetime duration compared to batteries and higher efficiency compared to motor-based generators. Drawbacks are the not existing infrastructure, the low storage density and the high cost of the required hydrogen as fuel.
For this reason ZBT together with partners is developing a LPG-based Reformer module for feeding hydrogen-based LT-PEM fuel cell systems. Bases are ZBTs reformer concept and desulphurisation unit, a web based control by Creative Electronic and E-PAC® by DMTpe suitable for mass production.
The high efficient module including peripheral components is a prototypical device with a high level of development in terms of functionality and manufacturing. It generates a synthetic gas with a hydrogen power output of 3 kW at a maximum CO concentration of 10 ppm. Internal energy storage enables an off grid operation.
Target application is the hydrogen generation for LT-PEM fuel cell systems for autarkic, decentralized energy or power supply or backup power for Telecommunication, BOSNet and further more remote lodges etc.
