In the present invention, a fuel cell
system is equipped with a fuel cell
, a fuel-supplying unit, a collecting unit, a first fluid flow path, a second fluid flow path, and a third fluid flow path. The fuel cell
generates power by consuming a fuel. The fuel-supplying unit feeds a circulatory fluid containing a fuel to the fuel cell

The invention provides a power supply system comprising a solar panel for generating electricity and a fuel cell
for supplying electricity to a load. The fuel cell
is regenerated using the electricity generated by the solar panel. This regeneration is based on supply and demand data for at least a full year cycle. In this way, an energy shift method is used to create an energy efficient system to store summer surplus energy, for either longer endurance or even over the winter. This fuel cell
system can for example break the geographical barrier for off grid street lighting system with high light output by downsizing the photo-voltaics while upsizing energy storage, thereby reducing cost compared to battery driven systems.

||PCT/CA2014/050263||SOCIÉTÉ BIC||MCLEAN, Gerard F.|
A method and system for supplying power to a portable electronic device includes supplying current from one or more fuel cells
to a DC-DC converter and regulating a current limit of the DC-DC converter as a function of a measured temperature of at least one of the power supply system and the portable electronic device. The current limit can vary as an inverse function of the measured temperature. The current limit can be an input current limit of the DC-DC converter or an output current limit of the DC-DC converter. Current produced by the one or more fuel cells
can decrease proportionally to a decrease of the current limit of the DC-DC converter, reducing the heat produced by the one or more fuel cells
and thereby reducing the measured temperature. A temperature sensor can be located on or near the one or more fuel cells
. A temperature sensor can be located on an internal housing of the portable electronic device.
