Description
Technical field
The invention belongs to fuel cell field, particularly relate to fuel battery engine system.
Background technology
For protection of the environment, reduce the air pollution in city, receive increasing concern with the device that PEMFC (Proton Exchange Membrane Fuel Cells) is power, when PEMFC with pure hydrogen for fuel time, it can reach real " zero " discharge.Current PEMFC all has certain application in the field such as traffic, communication.
The fuel battery engine system of prior art is provided with aerial cooler and hydrogen preheater, aerial cooler needs cool cycles water for cooling, hydrogen preheater needs cool cycles water preheat, because both institute's water requirements are inconsistent, therefore need from cool cycles pipeline, establish two branch roads, respectively to Air flow with to hydrogen preheating, its deficiency is that the conveying water yield of coolant circulation pump is large, and the energy consumption of coolant circulation pump is large.
Summary of the invention
The object of this invention is to provide a kind of fuel battery engine system, aerial cooler is combined with hydrogen preheater, the energy consumption of system is reduced.
Technical scheme of the present invention is: a kind of fuel battery engine system, comprise fuel cell pack, distribute assembly, hydrogen feed unit, air feed unit and cooling unit, air feed unit comprises filtering silencer and air compressor machine, hydrogen feed unit comprises air accumulator, electromagnetically operated valve, control valve member, water knockout drum and hydrogen tail valve, cooling unit comprises expansion tank, coolant circulation pump, filter, thermostat and heating tube, it is characterized in that described fuel battery engine system also comprises heat exchanger, cancel the humidifier of air feed unit, described heat exchanger is three stream heat exchanger, heat exchanger hot junction is air fluid, heat exchanger cold junction establishes two strands of respective separate stream, one is hydrogen fluid, another stock is cool cycles aqueous fluid, described three stream heat exchanger hot-side inlet are connected with air compressor exhaust port, and three stream heat exchanger hot junction outlets are connected with fuel cell pack air intake, three one fluid intakes of stream heat exchanger cold junction export with control valve member and are connected, three this fluid streams of stream heat exchanger cold junction outlets are connected with fuel cell pack hydrogen entrance, another fluid streams entrance of three stream heat exchanger cold junctions is connected with cooling unit cool cycles pump discharge, and three another fluid streams of stream heat exchanger cold junction outlets are connected with cool cycles pump intake, described hydrogen feed unit also comprises hydrogen refluxing portion, and hydrogen refluxing portion comprises electronic reflux pump, and electronic reflux pump pipeline is connected on the pipeline of water knockout drum exhaust outlet and heat exchanger cold junction hydrogen fluid issuing.
The invention has the beneficial effects as follows:
1, aerial cooler is combined with hydrogen preheater, is parts by two component integrations, simplifies system, reduce the energy consumption of system;
2, instead of air side humidifier with hydrogen backflow, reduce the volume and weight shared by single parts, instead of air side humidifier with hydrogen backflow, namely replace cathode humidification with anode humidification.Because negative electrode is that High Purity Hydrogen does fuel, anode is that air makees oxidant, and therefore anode air inflow accounts for about 1/10th of cathode inlet amount, and employing hydrogen backflow replacement air side humidifier reduces the volume and weight shared by single parts;
Do not contact between 3 fluid streams of 3, three fluid streams heat exchangers, mixed disturbing can not be produced;
4, in three stream heat exchanger, cooling circulating water supplements for air and the unmatched heat exchange of hydrogen heat exchange capacity.
