Fuel cell sets your house in order

A fuel cell group has unveiled a domestic device that it claims can meet the power needs of an entire household.

The NetGen fuel cell, which is around the size of a washing machine, has been developed by Australia’s Ceramic Fuel Cells (CFCL).

One NetGen unit can provide around 1kW of power, which should be enough to run all the appliances for the average household, according to CFCL’s head of European business Brendan Bilton.

He said the unit’s main advantage is its high energy efficiency. ‘Every kilowatt of electricity produces 1kW of heat. Compared to most other fuel cells, whose ratio is nearer two to one, we are making a huge gain in efficiency,’ he claimed.

One of the technical challenges the company faced in creating the system was dealing with the waste heat that is produced. A highly efficient heat exchanger had to be developed that could heat the incoming gas inside the fuel cell stack to the optimum temperature for power generation while dealing with the excess heat.
