PEM fuel cell stack factory talks about the composition and structure of fuel cells
PEM fuel cell stack plants discover that a fuel cell is an electrochemical energy conversion device that electrochemically combines a fuel (usually hydrogen) and an oxidant (usually oxygen) to generate electricity and heat.
The PEM fuel cell stack factory believes that the main components of a fuel cell are: electrodes, electrolyte membranes and current collectors.
The analysis electrode of PEM fuel cell stack can be divided into two parts, one is the anode and the other is the cathode. The electrode of a fuel cell is an electrochemical reaction site where the fuel oxidation reaction and the oxidant reduction reaction occur. The key to its performance depends on the performance of the catalyst, the material of the electrode and the process of the electrode.
2. PEM fuel cell stack plant electrolyte membrane
The main function of the electrolyte separator is to separate the oxidant and the reducing agent, and conduct ions, so the thinner the electrolyte separator, the better, but the strength also needs to be considered.
3. PEM fuel cell stack factory talks about current collectors
The current collector, also known as bipolar plate, has the functions of collecting current, separating oxidant and reducing agent, and diverting reaction gas. The performance of the current collector mainly depends on its material characteristics, flow field design and processing technology.
PEM fuel cell stack
Although fuel cell vehicles are developing rapidly, from the perspective of commercialization requirements, there is still a certain gap in China's vehicle fuel cell technology. In the future, it is necessary to strengthen the layout of the following aspects of the Wholesale PEM fuel cell stack:
china fuel cell stack is not the actual battery stacked together, but a fuel cell term, which refers to a battery stack composed of multiple fuel cells in order to obtain a practical voltage. china fuel cell stack The key is the material and manufacturing technology that make up the battery stack. China fuel cell stack materials must have sufficient chemical stability and thermal stability. The electrochemical performance must meet the requirements, and all technical conditions must also be consistent in order to obtain good benefits. Size and weight should be minimized.
