Water Electrolysis Technology
Water Electrolysis Technology – Spraying Fuel Cell Catalyst Inks – Cheersonic
The electrolysis of water, also known as water decomposition, utilizes electrical energy to decompose water into oxygen (O2) and hydrogen (H2) gases through electrolysis. The DC power supply is connected to two electrodes or two plates (usually made of inert metals such as platinum or iridium) placed in water. Hydrogen gas appears at the cathode (electrons enter the water), and oxygen appears at the anode. The hydrogen released in this way can be used as hydrogen fuel or remixed with oxygen to produce hydrogen oxygen gas.
There are three main technologies on the market: alkaline electrolyzer, solid oxide electrolyzer, and proton exchange membrane (PEM) electrolyzer.
Alkaline electrolyzers are cheaper in terms of investment, but have the lowest efficiency.
PEM electrolytic cells are more expensive (they typically use expensive platinum group metal catalysts) but have higher efficiency and can operate at higher current densities, so if hydrogen production is large enough, it may be cheaper.
Solid oxide electrolytic cells (SOECs) are the third most common type of electrolysis, using high operating temperatures to improve efficiency. The theoretical electrical efficiency of SOEC is close to 100% at 90% hydrogen production. Unlike PEM and alkaline electrolyzers, the degradation of the system over time initially does not affect the efficiency of the SOEC electrolyzer. As the performance of the SOEC system decreases and the battery voltage increases, more heat will naturally be generated in the system. Therefore, less energy is required to maintain system heat, which will compensate for the initial energy loss caused by rapid degradation.
The programmable bench top design ultrasonic spray coating machine UAC4000L is ideal for producing various uniform and durable coatings in R&D process. The UAC4000L integrated with different ultrasonic nozzles spraying width from 1 mm to 60 mm is widely designed for spraying PEM, GDL, Electrode and electrolyte membranes, by depositing solutions, suspensions as well as carbon black ink suspension, PTFE binder, ceramic slurry, platinum, platinum and other expensive metal catalysts. The operating system with multiple spraying methods is stable and easy to operate.
