Proton-exchange-membrane fuel cell, complete equipment and automatic control method

Abstract

The invention relates to a proton-exchange-membrane fuel cell, complete equipment and an automatic control method and belongs to the technical field of proton-exchange-membrane fuel cells. The proton-exchange-membrane fuel cell comprises a clamping plate and an upper clamping plate; a plurality of fuel cell plates are arranged between a lower clamping plate and the upper clamping plate in a stacking manner, and fixed rods are used for fastening the lower clamping plate and the upper clamping plate; temperature sensors are arranged between the adjacent fuel cell plates; the proton-exchange-membrane fuel cell is also provided with a hydrogen inlet pipe and an air inlet pipe which are respectively used for conveying hydrogen and oxygen into the fuel cell plates. The proton-exchange-membrane fuel cell provided by the invention has the beneficial effects that temperatures of all the cell plates can be effectively monitored and can be fed back to a remote monitoring end, so that the cell plates can run in a suitable temperature range.

Description

technical field [0001] The invention relates to a proton exchange membrane fuel cell, a complete set of equipment and an automatic control method, and belongs to the technical field of proton exchange membrane fuel cells. Background technique [0002] Proton exchange membrane fuel cell (PEMFC) is the fifth developed after alkaline fuel cell (AFC), phosphoric acid fuel cell (PAFC), molten carbonate fuel cell (MCFC) and solid oxide fuel cell (SOFC). The new generation fuel cell has the characteristics of small size, fast start-up, high energy conversion rate, low-temperature start-up, and no electrolyte leakage due to the use of solid-state electrolyte polymer membranes as the electrolyte. It has the advantages of low energy consumption, good reliability and maintainability, and has little environmental pollution. It hardly emits nitrogen oxides or sulfur oxides, and its CO2 emission is more than 40% less than that of conventional power plants. It is recognized as the most p...

Problems solved by technology

In terms of control methods, in view of the shortcomings of the traditional control strategy tracking temperature changes, such as hysteresis, large overshoot, and system coupling, a control method that follows pressure changes is proposed.
