As the world accelerates its transition toward sustainable energy solutions, hydrogen fuel cell technology is gaining significant traction in various industries, including transportation. SonnePower, a leader in electronic control systems, has leveraged its expertise in advanced controllers and displays to play a pivotal role in the development of hydrogen fuel cell vehicles.
Hydrogen, the third most abundant element in the Earth’s crust, is mostly found in compounds like hydrocarbons and water. It is relatively easy to extract hydrogen from these compounds using established technologies. Among these methods, using renewable energy sources such as solar and wind energy for hydrogen production, as well as employing biotechnology, are seen as some of the most promising future solutions.
Today, hydrogen is widely used in various industrial applications, including petroleum refining, glass production, ammonia synthesis, large-scale generator cooling, semiconductor manufacturing, and aerospace industries.
High Efficiency: Fuel cells can deliver efficiency levels that exceed twice those of traditional internal combustion engines.
Clean: Apart from electricity and heat, fuel cells only produce pure water—no carbon dioxide, carbon monoxide, nitrogen oxides, or sulfur compounds.
Quiet Operation: With minimal moving parts, fuel cells generate very little noise and vibration.
Reliability: Fuel cells have no mechanical wear and tear and do not require regular component replacement. They are not prone to sudden failures that interrupt power output, and unlike batteries, they do not experience self-discharge when not in use. Fuel cells also have a wider operating temperature range and better environmental adaptability than traditional batteries.
High Energy Density: Depending on the amount of fuel carried, proton exchange membrane fuel cells can offer energy densities several times higher than any current mainstream battery, including lithium-ion batteries.
While both fuel cell vehicles and pure electric vehicles (EVs) use electric energy to power motors, the key difference lies in how that energy is sourced. In fuel cell vehicles, the electricity is generated by a chemical reaction between hydrogen and oxygen, whereas in pure electric vehicles, energy is stored in batteries and used as needed.
For fuel cell vehicles, refueling with hydrogen is as simple as filling up a gas tank, allowing for a quicker refueling process and longer driving ranges. On the other hand, pure EVs require frequent, longer charging times to replenish battery power.
In hydrogen fuel cell vehicles, the fuel cell stack is the core component responsible for converting the chemical energy from hydrogen and oxygen into electrical energy. The fuel cell stack is typically packaged as a standalone unit, which receives hydrogen and oxygen and outputs electrical power. This unit is commonly referred to as a reactor.
For commercial and passenger vehicles, these reactors typically require two controllers to manage their functions. In a recent project with one of SonnePower’s clients, the main controller directly oversees the chemical reaction between hydrogen and oxygen. The secondary controller, using SonnePower’s D20N24 Series Controller, plays a crucial role in safety monitoring and system optimization. It is responsible for collecting temperature and pressure data, overseeing the reactor’s cooling system, water pumps, and ensuring safe operation. Additionally, it communicates with the vehicle’s driving system, working in conjunction with the main control unit to enhance the overall performance of the vehicle’s system.
SonnePower’s 7-inch Touchscreen Display is used to monitor reactor data, providing real-time feedback for operators. In smaller reactors, a single controller can be used to manage both internal reaction control and external safety monitoring. The high-quality display ensures smooth communication and effective data visualization, further optimizing performance and safety.
SonnePower’s cutting-edge electronic controllers and displays are helping to pave the way for the widespread adoption of hydrogen fuel cell vehicles. Their innovative solutions ensure that hydrogen-powered vehicles are not only efficient and environmentally friendly but also safe and reliable.
As the world moves toward a more sustainable future, the collaboration between advanced electronic control systems and hydrogen fuel cell technology will play a crucial role in transforming the automotive industry and contributing to global energy goals.
