Application

The fuel cell stack is the core of the fuel cell system, responsible for directly converting chemical energy into electrical energy. It achieves this by converting fuel, typically hydrogen, and oxygen into electricity and water through special reactions.

A fuel cell stack is composed of individual fuel cells connected together to generate electricity for various applications. Each fuel cell in the stack consists of two electrodes (cathode and anode) separated by an electrolyte. When hydrogen fuel and an oxidant (usually oxygen from the air) are provided to the fuel cell, a chemical reaction occurs at the electrodes, producing electricity.

The fuel cell stack finds applications in various fields, including fuel cell electric bicycles, communication base stations, unmanned aerial vehicles, portable power supplies, and backup power supplies.

Advantages

  • Efficient energy conversion: It can convert fuel into electrical energy with an efficiency of over 40%, far superior to traditional methods. This means it uses energy more efficiently and improves overall energy utilization.
  • Environmentally friendly: The stack runs on hydrogen or hydrogen-based fuel and produces only water and heat as by-products. It contains no harmful emissions and is green and environmentally friendly.
  • Stable and reliable: The fuel cell stack is simple in design, has no moving parts, and is very stable and reliable. It runs quietly and lasts longer than traditional energy devices such as internal combustion engines.
  • Fast start-up and response: Fuel cell stacks start up quickly and respond to energy demands without waiting for warm-up time, making them ideal for applications such as electric vehicles and drones.
  • Complementary with other energy sources: It can be combined with other energy systems to efficiently utilize and store various energy sources. For example, renewable energy sources such as solar and wind power can produce hydrogen for fuel cell stacks, which can then be converted into electricity for different uses.
  • In summary, fuel cell stacks are a versatile, clean and reliable technology for generating electricity from hydrogen and oxygen, offering fast response times and being compatible with other energy sources.

FAQ

What is a fuel cell stack?

A fuel cell stack is like a stack of building blocks, each of which is a fuel cell. These fuel cells work together to generate electricity using hydrogen fuel and oxygen. They can be connected in series to generate enough electricity for different purposes.

How does it work?

Each fuel cell in a stack has two sides: a cathode and an anode, separated by an electrolyte. A chemical reaction occurs when hydrogen gas is supplied to one side (the anode) and oxygen is supplied to the other side (the cathode). This reaction releases electrons, which create an electrical current that flows through an external circuit, generating electricity. The reaction also produces water as a by-product.

The composition of the fuel cell stack:

The main parts of a fuel cell stack include:- Fuel cells: These are self-contained power generating devices.- Bipolar plates: they act as support and help with electrical conductivity and temperature management.- Gaskets and Seals: Creates a tight seal to prevent leaks and maintain airflow.- End plates: they support the chimney and provide connections for fuel, oxidizer and coolant.- Gas Manifold: Channels that distribute fuel and oxygen to the fuel cells.- Coolant Manifold: A channel that takes heat away from the battery pack.- Electrical connectors and cables: These connect the fuel cell stack with external equipment to transmit the generated electricity.

How much power is generated?

A single fuel cell produces a low voltage, typically less than 1V, which is insufficient for most applications. In order to obtain enough power, many fuel cells are connected in series to form a fuel cell stack. The size of the stack and the power it generates depends on factors such as fuel cell type, size, operating temperature, and gas pressure used.
