Heating and heat preservation device for exhaust pipe of fuel cell car

The utility model relates to a heating and heat preservation device for an exhaust pipe of a fuel cell car. The device comprises temperature sensors, a data acquisition module, an interior computer, a heating layer and a heat preservation layer, wherein the temperature sensors are connected with the data acquisition module; the data acquisition module is connected with the interior computer through an internal circuit; the heating layer and the heat preservation layer are wrapped on the outer surface of the exhaust pipe in sequence from inside to outside. Compared with the prior art, the heating and heat preservation device overcomes the technical defects that the exhaust pipe is blocked by frozen water vapor in the exhaust pipe when a traditional fuel cell car works at zero DEG C to influence exhaust emission and car operation, the fuel cell car can be started and operated successfully under a low temperature environment, and the heating and heat preservation device has certain theoretical value and application value.
