Heating device for fuel cell reactor

Abstract

The invention adopts a technical project: a fuel cell reactor heater including a reformer, a reactor and a heater part, where, the reformer generates hydrogen gas from the supplied fuel; two sides of an electrolyte film in the reactor are respectively arranged with a fuel pole and an air pole, the fuel pole is supplied with the generated hydrogen gas or the fuel containing hydrogen gas and simultaneously the air pole supplied with oxygen gas or oxidant containing oxygen gas, it generates electricity and heat by the electrochemical reaction of the hydrogen with the oxygen; the heater part keeps a proper temperature inside the reactor and prevents the water in the reactor from freezing. The heater uses the heater part to maintain the internal temperature of the reactor above the set temperature and avoids the problem of not adapting to large electricity in the first period of driving.

Description

technical field [0001] The invention relates to a fuel cell reactor, in particular to a heating device for the fuel cell reactor capable of preventing the freezing of moisture inside the reactor and enabling the fuel cell to have a good initial drive. Background technique [0002] In general, a fuel cell is a device that converts the energy held by a fuel into electrical energy. Usually, in this kind of fuel cell, the two sides of the electrolyte are respectively provided with anode and cathode, wherein the anode (oxidation electrode or fuel electrode) is supplied with hydrogen or fuel gas containing hydrogen, while the cathode (reduction electrode or air electrode) is supplied with Oxygen is an oxidizing gas. In this process, the ionized fuel gas and oxidizing gas undergo an electrochemical reaction, and electricity and heat are generated. [0003] Such as figure 1 As shown, the fuel cell includes: a fuel tank 1, a reformer 2, a reactor 3, a power converter 4, and the li...

Problems solved by technology

[0008] However, the above-mentioned fuel cell, when the operating temperature is low, its reaction rate will be relatively slow, it is difficult to adapt to a large capacity load, and it cannot adapt to the use of a large amount of electricity in the initial stage of driving, and it will not be used for a long time in a colder place For the fuel cell, after the water inside the reactor 3 is frozen, the electrolyte membrane will lose the conductivity of ions, and the reactor 3 cannot work normally
