Ceramic Fuel Cells Limited says it has achieved an electrical efficiency of 60% from one of its natural gas powered fuel-cell home appliances while exporting electricity to the grid.

The efficiency figure marks a 10% improvement on previous figures released by the Melbourne, Australia-based company which uses fuel cells made from ceramic materials.

Ceramic Fuel Cells says it has also developed technology to allow the fuel cell unit to make its own water, meaning the unit can generate electricity without using mains water supply. This has significant benefits compared to conventional power plants, particularly as water becomes more scarce and expensive, the company says.

‘This milestone takes our company to a new level, we have now achieved 60% efficiency in a fully integrated fuel cell and heating system, while exporting 1.5 kW of electricity to the grid,’ said managing director Brendan Dow.
