Fuel cell is heated using the heating device in secondary circulation loop, when cooling water of fuel cell outlet temperature is greater than 5.5
DEG C when judgement be cold-started successfully.Such mode needs additional energy source to fuel cell heating, for the angle of using energy source, no
It is most preferably.
In patent US6764780B2 by the way of anoxic load operating fuel cell, which passes through increasing fuel electricity
Pond internal resistance improves the temperature of fuel cell, although this method is simple, since oxidant and fuel flow rate are too low
Be difficult to control, the problem of not only fuel battery voltage being be easy to cause to reverse, but be easy to because load it is improper caused by membrane electrode it is permanent
Property is burnt out.Patent CN201320253808.1 using in such a way that fuel battery inside is placed in heating sheet, be although convenient for by which
Control, but easily lead to short circuit, and which needs to process the mounting groove of special installation membrane electrode, easily leads to pile leakage.
