As we are moving to cleaner and renewable energy sources, fuel cells have become more popular. Fuel cells consume hydrogen to produce electricity by mixing it with oxygen. On the other hand hydrogen is highly explosive, which means that as a fuel it could be potentially dangerous. Hydrogen Pressure Sensors - Key Component in Safe Operation of Fuel Cells
The sensors are used to sense and control the state of charge and assist in reducing parasitic overvoltage.ges stored within the fuel cell. This allows exact and real-time control over the whole fuel cell system. Fuel Cell applications would not be safe and functional without trusty pressure sensors.
Hydrogen pressure sensors are important not only in the field of fuel cell technology but also in many other industrial areas where hydrogen is used. An example is the chemical industry use hydrogen as a feedstock in the production of ammonia and other chemicals. As well as in the electronics industry, for fabricating semiconductors and flat panel displays.
In these industrial applications, detecting the pressure of hydrogen is also vital to prevent leakage and maintain safe operations. A major potential threat is from a hydrogen leak which could lead to fire or explosions. To monitor your pressures in real time as the signal alerts you to any early pressure changes, these sensors present. This ensures the rapid response and safe way to run hydrogen-related processes.
With the increasing use of hydrogen as a fuel, there is also an increased demand for more innovative pressure sensors. Some of the most important areas for advances include more miniaturized, higher-precision and longer-life sensors based on microelectromechanical systems (MEMS) technology. The ability to monitor hydrogen pressure in e.g. fuel cells And other systems with high precision is possible by integrating these tiny sensors into devices such as smartphones and wearable technology
The team is also looking to incorporate use of wireless sensors for realtime communication/information exchange with other devices and existing systems."I am fortunate being associated with the research division which encourages innovation. A fuel cell system or an industrial process designed with wireless hydrogen pressure sensors strategically placed at multiple locations would be able to monitor the pressures uninterrupted. The data the devices contribute can be harnessed to improve performance and safety.
Energy usage is not trivial and energy-efficient wireless hydrogen pressure sensors are very attractive as a result. These sensors provide a real-time data stream and ensure efficient fuel cell systems management around the clock. Such optimization can ultimately reduce waste and improve productivity using resources, such as hydrogen fuel.
In addition, wireless sensors can deliver predictive maintenance information so that potential problems are known well in advance of becoming a significant problem. This proactive posture reduces unplanned downtime and maintenance costs, contributing to enhancing fuel cell system performance as well as industrial process efficiency.
Despite the different hydrogen pressure sensors available, not all were made equal. Other sensors may be more appropriate in some applications, designed for the desired high accuracy specifications and low cost to provide adequate operational requirements High Level: Piezoelectric sensors are a good example for high-pressure applications because they have great accuracy and also outstanding stability. But they are a bit more expensive and need to be handled with care so as not to break them.
However, capacitive sensors tend to be more cost-effective and robust in nature - which is why they are an apt option for applications that require a low-cost solution with reliable performance. Things to consider when choosing the right sensor for an application include accuracy,needed life time,cost,ease of notice ( plug and play).
To summarize, hydrogen pressure sensors have an essential function in the successful and secure running of fuel cell systems which exploit hydrogen as well are used to control industrial processes where that same gas is required. As sensor technology continues to improve, we are likely to see the subsequent generation of increasingly accurate and reliable sensors that will only further catalyze hydrogen economy expansion.
