Daihatsu Motor Co Ltd exhibited two mock-ups of fuel-cell systems for residential and outdoor use at the 43rd Tokyo Motor Show 2013.
For the systems, Daihatsu intends to use fuel cells using liquid fuel. The fuel cells are being developed by the company for its vehicles.
One of the two systems, "FC-Dock 20C," has a maximum output of 2kW and is designed for residential use. With 20L of liquid fuel, it can generate 10kWh of electricity, which is equivalent to the amount that a household consumes per day. Because it is a stand-alone type that operates without an external power source, it can be used in a time of emergency.
The other system is the "FC-Dock 05C," which is expected to be used for camping and other outdoor uses. When equipped with four 1.2L liquid fuel cartridges, it can output 100W of electricity for 12 to 15 hours. Its maximum output power is 500W. It has a handle and casters for portability.
While many automakers have chosen hydrogen gas as a fuel for their fuel-cell cars, Daihatsu employed a liquid fuel that contains a hydrazine hydrate. Though it eliminates the need for precious metals such as platinum, it is difficult for the company to build infrastructures by itself. Therefore, Daihatsu exhibited the fuel-cell systems for residential and outdoor use at the show in the aim of increasing the number of "fellows," it said.
