Abstract

The invention belongs to the field of liquid fuel cells. The invention relates to a method for low-temperature fast start-up of a liquid fuel cell system. The method is characterized in that organic small molecular substances such as methanol and ethanol are used as fuel and catalytically combusted in a catalytic combustor, and the heat generated by combustion is directly or indirectly used to heat an electric pile through an electric pile heating chamber and / or to heat a water and heat management component in the system, so as to quickly start the liquid fuel cell system at low temperature. Compared with the prior art, the method helps to start the liquid fuel cell system at low temperature, improve the low-temperature environment adaptability of liquid fuel cells and expand the application scope of liquid fuel cells.
