The structure

function of key components

and preparation method of melting carbonate fuel cells(MCFC) have been briefly stated

a 200×200 mm single cell of MCFC being assembled

the max.current density of which can reach 0.1 A/cm2.On the basis of successful test for the single cell

a 560×400 mm bipolar plate of MCFC has been designed and fabricated

and a 300 W MCFC stack being assembled

the max.DC voltage of said stack being 3.3 V

the average voltage being 2.8 V

the max.current reaching 120 A

and the max.power output reaching 200 W.The test result has verified the performance of designed large area bipolar plate

providing experiences for developing a 10 kW MCFC system.
