Fuel cell power packs

The fuel cell power pack includes the fuel cell power module, an ultracapacitor storage unit, hydrogen storage tanks, thermal manage-... 

Since these forklifts had previously been powered by heavier batteries, one issue in the modification was weight. The fuel cell power pack itself was relatively easy to integrate into the equipment since it was smaller and lighter than the lead acid battery system. But, since the battery provided part of the counterbalance, additional weight was added to provide enough stability for the forklift.

As previously discussed (Sect. 5.5), the battery pack of a fuel cell power train can be either minimized assigning the role of generating most energy required by the load to the fuel cell stack (soft hybrid), or sized in order to provide all dynamic requirements of the vehicle allowing the utilization of a smaller FCS (hard hybrid). 

Because of the low operating temperature and ease of fabrication for low power units, PFFCs are the most likely fuel cell to be introduced in portable power packs. PFFCs in sizes of 300—500 W are being considered as a power source, eg, 4-h duration, 300 W, 1.2 kW, for the modem soldier operating in the enclosed environment of a self-contained protective suit, which has faciUties for air conditioning, radio communication, etc. Analytic Power Corp. (Boston) is assessing the use of PFFCs for this appHcation. 

GM also announced the expansion of fuel cell development activity with Giner, Inc., to include applications beyond the transportation field, including hydrogen generation for refueling systems and regenerative fuel cells for stationary power. GM s fuel cell stack set a new world standard for power density that packed 60% more power. The new stack generated 1.75 kilowatts (kW) per liter. 

Shipments of fuel cell-equipped mobile devices could grow very rapidly if they can eliminate the need for frequent recharging of current battery-powered models. The Medis 24/7 Power Pack in April 2007. It is a portable, disposable power source for small electronic devices such as cell phones and MP3 players. Manufactured by Medis Technologies, it is based on Direct Liquid Fuel cell technology, and may be of particular utility in military applications. Elsewhere, MTI MicroFuel Cells manufactures a power pack for portable electronics that is based on direct methanol fuel cell technology that it calls Mobion.
