Fuel Cell microCHP Generators
What is microCHP fuel cell technology?
A fuel cell is an electrochemical cell that directly generates electricity and heat from hydrogen rich fuels. This process is often accelerated by a catalyst such as a transition metal or an acid solution. Fuel cells operating at high temperatures (>600°C) do not require catalysts. The technology is similar to a battery in that it creates a DC charge from a chemical reaction, however fuel cells cannot store electrical energy they just produce it, as long as there is a continuous supply of fuel and air.
These systems are more expensive than their Stirling engine counterparts, but offer higher electrical efficiencies of around 55%, benefitting by operating through a clean electrochemical reaction rather than through combustion.
As with the other prime movers, waste heat is produced, which can then be recovered and used for heating, further increasing the overall efficiency of their process.
They offer significantly higher electrical efficiencies (30-45%) and good transient performance, which promises the potential to deliver the greatest benefits for residential energy production and if fuelled on pure hydrogen they produce no CO2 at all.
Fuel cells produce electricity though a silent electrochemical reaction, generating it considerably more efficiently than the other methods on the market currently.
