Hydrogen fuel cell capable of uniformly supplying energy, engine and automobile

Abstract

The invention discloses a hydrogen fuel cell capable of uniformly supplying energy, an engine and an automobile. The hydrogen fuel cell capable of uniformly supplying energy comprises an inflow main pipeline, sensors, a switch valve, a controller, a plurality of inflow branch pipelines and a plurality of galvanic pile groups, the single inflow branch pipeline communicates with the single galvanicpile group, the plurality of inflow branch pipelines all communicate with the inflow main pipeline, the sensors and the switch valve are both located on the inflow branch pipelines, the controller iselectrically connected with the sensors and the switch valve, and the controller can control the opening degree of the switch valve. The hydrogen fuel cell according to the present invention is provided with the sensor on each inflow branch line, the reaction condition in each galvanic pile group can be monitored and fed back to the controller, and the opening degree of the switch valve is adjusted through the controller so as to adjust the amount of gas or cooling water flowing into the branch pipelines from the main pipeline, so that the gas or cooling water is matched with the current reaction condition of the galvanic pile groups, thereby avoiding waste or insufficient supply.

Description

Technical field [0001] The present invention relates to the field of hydrogen fuel cells, in particular to a hydrogen fuel cell, an engine and an automobile capable of uniformly supplying energy. Background technique [0002] Fuel cell is a device that converts the chemical energy of fuel into electrical energy, also known as electrochemical generator. It is the fourth power generation technology after hydropower, thermal power and atomic power. Because the fuel cell converts the Gibbs free energy in the fuel chemical energy into electric energy through an electrochemical reaction, it is not limited by the Carnot cycle effect, so the energy conversion efficiency is high. The hydrogen fuel cell uses hydrogen and oxygen as raw materials and has no mechanical transmission parts, so there is no noise pollution and less harmful gas emissions. Therefore, hydrogen fuel cells have received more and more attention in energy safety and environmental pollution, and their applications have ...

Problems solved by technology

However, usually there are individual differences in each stack group, and the degree of reaction is different. Therefore, the amount of gas and cooling water required for the reaction of each stack group is different. For cooling water, it will cause some stacks to be over-supplied and wasteful, while others will be under-supplied
