System Overview
Nexa® Integration System
The Nexa® Integration System includes the 1.2 kW Nexa® 1200 Fuel Cell Power Module including a startup kit, the Nexa® DC 1200 DC/DC Converter (24 V or 48 V) and the Nexa® OSC Overall System Control Software to easily set up and run the system in laboratory environments.
For more complex laboratory setups and integration projects a range of accessories is available.
Nexa® Integration System for operation in laboratory environments.
Accessory program for more complex laboratory setups or integration projects and research projects.
The Nexa® 1200 Fuel Cell Module is the core of the Nexa® Integration System.
The fully integrated fuel cell power module is based on the FCgen™ 1020 ACS stack from Ballard, offering superior fuel efficiency and a long service life. Its enclosed, robust housing with integrated profile rails allows for comfortable integration of the module and protects the inner life of the system.
In combination with the Nexa® DC1200 DC/DC Converter and the Nexa® OSC Software facilitating overall system control, the Nexa® Integration System is optimal for implementing stationary applications.
System Features Nexa® 1200
Nexa® Integration System
Improved Overall System Efficiency
Whilst the old Nexa® Power Module required a compressor and a fan for the supply of reaction and cooling air, the Nexa® 1200 uses a single fan on the back of the system, drawing in ambient air for even distribution through the entire system. The parasitic power consumption could be reduced by up to 50%.
Improved Service Life
Heliocentris guarantees a system warrenty of 1500 hours, if the system is used according to specifications - three times the service life of the old Nexa® Power Module.
No Draining of Water Required
The open cathode stack facilitates drainage of the water accumulated during the reaction. It is evaporated with the cooling air and is blown out through the air duct at the back of the system. The air outlet is designed for easy attachment of an exhaust air duct.
Central Interface Unit and Mounting Rails
The Nexa® 1200 has a central, easy to reach interface unit on its back, housing peripheral, electrical and hydrogen connectors. Integrated mounting rails further facilitate the integration.
Scope of Delivery
Nexa® 1200 - Item 1911
Nexa ® 1200 Fuel Cell Power Module
Fully integrated 1.2 kW fuel cell power module comprising the FCgen™ 1020 ACS stack from Ballard. Integrated profile rails allow for flexible mounting of the system. All interfaces are located in one place on the system’s backside facilitating the connection of cables and hydrogen supply
Remote Control Software
The included Remote Control Software allows to put the Nexa® 1200 into operation and monitor all relevant operating parameters, e. g. stack voltage, stack current, coolant temperature and load state. All data can be saved for further editing
Startup Kit
The startup kit facilitates operation of the system in the lab. It comprises a load cable, a power relais, a diode with cooling element, a bundle of connectors and all necessary electric lines.
Nexa ® DC1200
The Nexa® DC 1200 DC/DC Converter stabilizes the unregulated fuel cell voltage of the Nexa® 1200 Fuel Cell Module to 24 / 48 Volt direct current. It also protects the system against reverse currents. The Nexa® DC1200 is required to hybridize the Nexa® 1200 with the optionally available Battery Set..
Hybridization Kit
The included Hybridization Kit ensures that the DC/DC Converter, the Nexa® Fuel Cell Module and the Set of Batteries work together safely as a fuel cell/battery hybrid system. The device is responsible for load control, battery control, battery charging and deep charge protection.
Software
The included software of the Nexa® DC1200 enables the central parameterization of the device and the visualization of its operation parameters via a MS Windows PC. Data logging for further analysis is possible.
OSC Software
Nexa® Integration System
Nexa ® OSC Software
The Overall System Control Software enables the central operation and configuration of the main components included in the Nexa® Integration System via a regular MS Windows PC:
» Nexa® 1200 Fuel Cell Module
» Nexa® DC1200
» EL 2400 Electronic Load
Component parameters are visualized in the software and can be logged and exported for further editing.
Hydrogen Supply
Nexa® Integration System
Metal Hydride Canister
The low-pressure metal hydride canister allows for safe and easy intermediate storage of 760 sl of hydrogen in a compact form. An integrated quick coupling ensures safe connecting and disconnecting of the canister.
H2 Connection Kit 200 bar
For direct operation of the Nexa® 1200 Fuel Cell Module or refilling of Metal Hydride Canisters from compressed gas cylinders. The pressure reducer ensures that the cylinder pressure is reduced to the suitable inlet pressure of the Nexa® 1200 or Metal Hydrid Canister.
H2 Connection Kit 15 bar
For connecting three Metal Hydride Canisters to the Nexa® 1200 Fuel Cell System.
HG60 Hydrogen Generator
The HG60 produces 60 standard liters of hydrogen per hour through the electrolysis of de-ionized water. No free acids or alkalines are used.
Through an innovative and maintenance-free gas dehydration system the generator achieves a hydrogen purity of 6.0 (99.9999 %). It is suitable for the refilling of low-pressure metal hydride canisters.
I/O Board
The I/O Board enables remote control of the hydrogen generator via RS232 interface. It allows to check the status of the generator and to control the production of hydrogen with a Windows PC. If equipped with an I/O board up to ten generators can be cascaded via RS485 interfaces.
The included software allows for monitoring of all relevant parameters, e. g. H2 production, pressure, cell voltage and operation time via PC.
