2) How DMFC systems work
The set-up of a DMFC system takes just a few minutes. Once linked to a battery and a fuel cartridge the system is ready to provide almost instantaneous power to a load.
- In essence the fuel cell acts as a dedicated charger for the battery which in turn accepts the load. The fuel cell controller then monitors the voltage of the battery and once this drops below a specific value (set generally at a default of 12.3V but fully customisable), the unit will automatically start up, charge the battery back to full capacity and then shut down switching into “monitor” mode until the battery voltage drops once again.
- This cyclical charging programme effectively provides an infinite battery run-time as long as fuel can be supplied to the unit. Run times from single fuel cartridges can provide up to 52 days of continuous use (dependent on load and size of fuel cell unit) however due to the cyclical operation of the unit where the fuel cell is not continuously running, these run times can be extended hugely.
- And now, with the recent introduction of the new DUOCART SWITCH into the product range, 2 fuel cartridges can be easily connected, effectively doubling the run time between cartridge changes.
- This simple but ingenious system makes the product ideal for extending battery runtimes to an almost unlimited period and is an ideal solution to replace the cost and manpower involved in continually replacing batteries in remote power applications such as remote monitoring, traffic signalling, security systems and other areas which currently use battery-intensive systems.
