The key to cost reduction is the membrane electrolyte assembly
In today’s energy crisis and increasingly serious environmental problems, energy-saving and low-emission energy sources such as solar photovoltaic power generation, lithium-ion batteries and hydrogen fuel cells have attracted the attention of countries all over the world. Among them, hydrogen fuel cells are considered very promising due to their sustainable fuel supply and the fact that only water is the by-product of fuel cells. Despite the great progress made by automakers, the commercialization and widespread adoption of vehicles powered by fuel cell systems is still in progress. The difficulty is the cost and durability of such systems.
Specifically, the key to reducing costs and extending fuel cell durability is the membrane electrolyte assembly. In this module, electrochemical reactions take place on both sides and protons are conducted internally through the membrane. In addition, the complex mass transfer of oxygen and water also directly affects the performance of fuel cells. Improving the activity of the catalyst and optimizing the structure of the catalyst layer are very important to reduce the activation voltage loss and proton conduction resistance. To increase the efficiency of fuel cells, the allowable current density is gradually increased, and at the same time the conflict between oxygen transport and water removal is more serious, because both the oxygen consumption rate and water production rate are directly proportional to the current density. In order to better understand the physical and chemical processes inside the membrane electrode assembly, many scholars have conducted research on mathematical models and experiments.
Cheersonic’s ultrasonic coating systems are used in a number of electrolysis coating applications. The high uniformity of catalyst layers and even dispersion of suspended particles results in very high efficiency electrolyzer coatings, either single or double sided.
