This is a very interesting development!!
"Viewed from a fourth aspect, there is provided a power supply system for charging or powering an electrical device, comprising an example disclosed electrochemical stack according to the third aspect, and a power supply control system electrically connected to the electrochemical stack and having a connector mechanism for allowing the power supply control system to be electrically connected to an electrical device, operable to charge or power the electrical device. For example, the power supply system may be configured for charging the battery of an electric vehicle (EV); or for an uninterrupted power supply (UPS), operable to power an electrical apparatus; or for generating power for a cellular telecommunications transmitter; or for some other stationary power system. In some example arrangements, the power supply system may comprise an ammonia cracker system for processing ammonia to produce hydrogen gas; and a fuel conveyor channel connecting the ammonia cracker system to the electrochemical stack, operable to convey the hydrogen gas from the ammonia cracker system to the electrochemical stack. The fuel gas may consist predominantly of hydrogen, where 99.999% is hydrogen. Alternatively, the percentage of hydrogen might be 99.95%, or 99%. It is also envisaged that the fuel could be -75% hydrogen, -25% nitrogen with up to 1 ,000 parts per million of ammonia. The hydrogen may be supplied by an ammonia cracker system, as mentioned above, or it may be supplied by a steam methane reformer, which can utilise methane or biomethane. The hydrogen may also be supplied by an electrolyser. Hydrogen produced using an ammonia cracker system might have a composition of -75% hydrogen, -25% nitrogen and 0 to -1 ,000 parts per million of residual ammonia."
And in the Claims:
15. A power supply system (600) for charging or powering an electrical device, comprising an electrochemical stack (500) as claimed in claim 14, and a power supply control system (610) electrically connected to the electrochemical stack (500), and having a connector mechanism (612), operable to electrically connect the power supply control system (610) to an electrical device.
16. A power supply system (600) as claimed in claim 15, comprising an ammonia cracker system (620), for processing ammonia to produce hydrogen gas; and a fuel conveyor channel (622) connecting the ammonia cracker system (620) to the electrochemical stack (500), operable to convey the hydrogen gas from the ammonia cracker system (620) to the electrochemical stack (500).
17. A power supply system (600) as claimed in claim 15 or 16, configured to charge an electric vehicle.
