Fuel cell stack

Polymer electrolyte membrane PEM fuel cells are the current focus of research for fuel cell vehicle applications. PEM fuel cells are made from several layers of different materials. The main parts of a PEM fuel cell are described below. Hardware components used to incorporate an MEA into a fuel cell include gasketswhich provide a seal around the MEA to prevent leakage of gases, and bipolar plateswhich are used to assemble individual PEM fuel cells into a fuel cell stack and provide channels for the gaseous fuel and air.

The membrane, catalyst layers anode and cathodeand diffusion media together form the membrane electrode assembly MEA of a PEM fuel cell. The polymer electrolyte membrane, or PEM also called a proton exchange membrane —a specially treated material that looks something like ordinary kitchen plastic wrap—conducts only positively charged ions and blocks the electrons.

The PEM is the key to the fuel cell technology; it must permit only the necessary ions to pass between the anode and cathode. Other substances passing through the electrolyte would disrupt the chemical reaction. For transportation applications, the membrane is very thin—in some cases under 20 microns.

A layer of catalyst is added on both sides of the membrane—the anode layer on one side and the cathode layer on the other. Conventional catalyst layers include nanometer-sized particles of platinum dispersed on a high-surface-area carbon support.

This supported platinum catalyst is mixed with an ion-conducting polymer ionomer and sandwiched between the membrane and the GDLs. On the anode side, the platinum catalyst enables hydrogen molecules to be split into protons and electrons.

On the cathode side, the platinum catalyst enables oxygen reduction by reacting with the protons generated by the anode, producing water. The ionomer mixed into the catalyst layers allows the protons to travel through these layers.

The GDLs sit outside the catalyst layers and facilitate transport of reactants into the catalyst layer, as well as removal of product water.

Each GDL is typically composed of a sheet of carbon paper in which the carbon fibers are partially coated with polytetrafluoroethylene PTFE. Gases diffuse rapidly through the pores in the GDL. These pores are kept open by the hydrophobic PTFE, which prevents excessive water buildup.

In many cases, the inner surface of the GDL is coated with a thin layer of high-surface-area carbon mixed with PTFE, called the microporous layer. The microporous layer can help adjust the balance between water retention needed to maintain membrane conductivity and water release needed to keep the pores open so hydrogen and oxygen can diffuse into the electrodes. The MEA is the part of the fuel cell where power is produced, but hardware components are required to enable effective MEA operation.

Each individual MEA produces less than 1 V under typical operating conditions, but most applications require higher voltages. Therefore, multiple MEAs are usually connected in series by stacking them on top of each other to provide a usable output voltage. Each cell in the stack is sandwiched between two bipolar plates to separate it from neighboring cells.

These plates, which may be made of metal, carbon, or composites, provide electrical conduction between cells, as well as providing physical strength to the stack. Additional channels inside each plate may be used to circulate a liquid coolant.

Each MEA in a fuel cell stack is sandwiched between two bipolar plates, but gaskets must be added around the edges of the MEA to make a gas-tight seal. These gaskets are usually made of a rubbery polymer. Skip to main content. Parts of a Fuel Cell.

Just like batteries, individual cells are stacked to achieve a higher voltage and power. This assembly of cells is called a fuel cell stack, or just a stack. The power output of a given fuel cell stack will depend on its size.

Increasing the number of cells in a stack increases the voltage, while increasing the surface area of the cells increases the current. A stack is finished with end plates and connections for ease of further use. Below you will find many stacks that can easily be integrated into a system to provide an operational power system tailored for most specific applications. We even offer DIY and build it yourself fuel cell stacks and kits.

ACC helps you maintain a set following interval behind a detected vehicle for highway driving. If the detected vehicle slows to a stop, ACC is designed to slow and stop your vehicle as well. After stopping, a tap on the throttle instructs the car to continue maintaining the desired interval. RDM can determine if you cross over detected lane lines without signaling, can provide steering assistance to help you return to your lane or provide braking to help you keep from leaving the roadway entirely.

With your hands on the steering wheel, long highway drives are easier with LKAS. It subtly adjusts steering to help keep the vehicle centered in a detected lane.

While all three powertrains use an electric drive motor, there are several differences that allow each vehicle to suit various lifestyles and driving uses. Fuel-cell vehicles typically have range ratings of miles or more and refueling times of approximately 5 minutes or less, along with a highly efficient fuel cell to create the on-demand electricity for power with no emissions.

A battery-electric vehicle BEV obtains its power from electricity stored in highly efficient and powerful batteries that require recharging via a power outlet.

A BEV also produces no emissions and has range ratings that can vary from 50 to miles, depending on battery capacity.

By utilizing this hybrid powertrain, the vehicle can be driven fuel-efficiently for long driving distances. When driven in EV mode, it produces zero emissions. The battery can be recharged from a power outlet much like a battery-electric vehicle.
