Fuel Cells Bulletin 11 efficient. High capital costs, lifetime performance and the inability to handle intermittent and varying loads are also current drawbacks.
CSIRO is developing a solid-state system based on polymer electrolyte membranes for on-demand, distributed hydrogen production. At present the unit runs on mains power, but researchers are investigating how to power it with renewable energy, such as solar and wind.
The hydrogen generated can be stored for long periods and converted to electricity when needed. The ability to generate energy on-site and on-demand would reduce up-front infrastructure costs. Badwal says the team is still in the R&D stage, but it 'would like to have a commercial partner on board, as full-scale commercialization is three to four years away.'

Kyocera's 1 kWe class SOFC power generation systems are based on its proprietary flat tube cells. The company achieved the world's most-efficient power generation of 54% in December 2003, and demonstrated that it could deliver the basic performance that supports household operations, and adjustment
Passive, stand-alone, direct methanol fuel cells require a pressure management system that releases CO 2 produced in the anode chamber. However, this must be done without allowing the methanol fuel to escape. In this paper, two siloxane membranes are investigated and shown to selectively vent CO 2 f
The hybrid direct carbon fuel cell (HDCFC), combining molten carbonate fuel cell and solid oxide fuel cell technology, is capable of converting solid carbon directly into electrical energy without intermediate reforming. Here, we report the investigation of the HDCFC with yttria stabilized zirconia
