oxygen sensor oxygen battery
OX-1 oxygen sensor is also called OX-1 oxygen battery.
The principle of a fuel cell is an electrochemical device with the same composition as a general battery. The single cell is composed of two electrodes (a negative electrode is a fuel electrode and a positive electrode is an oxidant electrode) and an electrolyte. The difference is that the active material of a general battery is stored inside the battery, thus limiting the battery capacity. The positive and negative electrodes of a fuel cell do not contain active materials, but are only catalytic conversion elements. Therefore, fuel cells are truly energy conversion machines that convert chemical energy into electrical energy. When the battery is operating, fuel and oxidant are supplied from the outside and react. In principle, as long as the reactants are continuously input and the reaction products are continuously eliminated, the fuel cell can continuously generate electricity.
significance:
① Hydrogen is a multi-element in the world. The source of hydrogen is extremely extensive and it is a renewable resource, so it seems appropriate to use hydrogen as a “fuel”.
② Since the fuel cell converts chemical energy directly into electrical energy, it does not generate a large amount of exhaust gas and waste heat compared with the combustion of the internal combustion engine, and the conversion efficiency can exceed 50% (the internal combustion engine conversion efficiency is 10%). The emissions are only water, and Affects the ambient temperature.
③ The service life is longer than that of electrochemical cells and the battery maintenance workload is small.
④Compared to the charging time of pure electric vehicles, the time for fuel cells to fill hydrogen is very short, which is almost the same as the time for adding fuel to internal combustion engines, about 3-5 minutes.
A fuel cell is an electrochemical power generation device. It is different from batteries in the conventional sense. The main principle is that the fuel cell directly converts chemical energy into electrical energy according to an electrochemical method. It does not go through the heat engine process, so it is not limited by the Carnot cycle, and has high energy conversion efficiency (40-60%); it produces almost no NOx and SOx emissions. Moreover, CO2 emissions are reduced by more than 40% compared to conventional power plants. Because of these outstanding advantages, the research and development of fuel cell technology has received much attention from governments and large companies in various countries. It is considered to be the preferred clean and efficient power generation technology in the 21st century. When it works, the oxidant and reducing agent can be continuously from the outside Input, and at the same time continuously discharge the electrode reaction products out of the battery, directly convert the chemical energy of the fuel combustion reaction in the energy source into electrical energy.It has the advantages of high energy conversion rate and sustainable use.

Since the OX-1 oxygen sensor, OX-2 oxygen sensor and OX-5 oxygen battery are trace oxygen sensors, they need to be isolated from the air and packed in nitrogen, so when not in use, they need to be kept in a nitrogen-filled bag at all times. When you take it out, you need to put the trace oxygen sensor into the instrument immediately and purge it with inert gas. <span style = “white-space: normal;”> Keywords: American GE | Oxygen Analyzer | Micro Oxygen Analyzer | OX-1 Oxygen Sensor | OX-2 Oxygen Battery | OX-3 Oxygen Sensor | OX-4 Oxygen Battery | OX-5 oxygen sensor | dew point meter | biogas analyzer | headspace analyzer
In addition, when using OX-1 oxygen sensors including OX-2 | OX-3 | OX-4 | OX-5 oxygen batteries, we must pay attention to the pressure. It is better to control the pressure below 1 kg, because the OX-1 oxygen sensor is internal There is a membrane, the pressure will break through the membrane and cause leakage of the OX-1 oxygen sensor. Any leakage is not covered by the warranty.
