A fuel cell is an electrochemical device that generates electricity by converting the chemical energy stored in fuel to electrical and thermal energy. Instead of burning fuel, as in the case of an internal combustion engine, it generates power using an electrochemical reaction. The by-products of the electrochemical reaction are pure water, carbon dioxide, and heat.
No, there are many different types of fuel cells. Some of the key differences are in the type fuel they use, the way they are built, and their operating conditions such as temperature and environment. Uses range from powering small consumer devices to generating electricity for power plants. The application dictates the type of fuel cell required.
Fuel cells themselves are not a power source: rather they use a fuel to produce electrical power. If the fuel is obtained from renewable sources, then fuel cells can be an important part of the renewable energy chain.
We designs, develops, and manufactures liquid methanol-based fuel cells.
A battery chemically stores and releases electricity, while a fuel cell produces energy through the electrochemical reaction of a fuel and air. A battery runs out of power and requires recharging. A fuel cell, however, continues to function and produce power as long as fuel and oxygen are supplied.
Our products have few moving parts and require little maintenance. However, when required, our large dealer network can provide labor and parts for on-site service. Our dealers offer a number of maintenance plans to cover all operating environments.
A variety of fuels can be used, including hydrogen, methanol, ethanol, butane, natural gas, ammonia, and liquefied petroleum gas. Energy from landfills, biomass, coal, wood, and agricultural waste can also be used to create the fuel. Because they function on such diverse input, fuel cells are a logical choice to transition from current combustion-based technologies to renewable energy sources.
Methanol is delivered to the fuel cell, similar to refueling a car. A compact methanol-refueling cabinet with a hose and nozzle is used to transfer methanol to the fuel tank in our products. Anyone can refuel the DMFC fuel cells with minimal training.
Methanol delivery for our customers is ensured by us. We have set up partnerships with several large national methanol suppliers so that the fuel can be regularly supplied to any location within one business day.
There are other options for refueling, such as using a hand pumps or swapping tanks. However, these options are not standard and are customized based on the unique needs of our customers.
The standalone unit can work with 24V and 48V battery systems. The hybrid unit currently replaces only the 24V batteries.
Yes, DMFC products can operate in freezers without any negative impact on DMFC performance or life. Our products have been operationally tested at conditions below –4ºF/–20ºC.
Yes, with our fuel cells installed, vehicles can be completely independent of the grid.
A single DMFC refueling station holds two 55-gallon drums of methanol. A 55-gallon drum can supply fuel to 15 DMFC units that are completely out of fuel before the 55-gallon refueling rig is emptied. After that, the drum will need to be replaced before additional refuels can take place. Replacing a drum takes only a few minutes, after which another 15 DMFC units can be refueled before the second drum needs to be replaced. Therefore, the DMFC fueling rig can support many DMFC units.
No, the refueling station is a NFPA 30 rated cabinet with compression fittings at all connection points. Additionally, all the couplings on the refueling station are self-sealing couplers with an in-line dry-break coupler, in case a driver forgets to disconnect before driving away.
No, a trickle charge is the best type of charge for batteries as it does not heat the battery. The only drawback to trickle charging is time; however, because the DMFC unit is mounted on and connected to the battery at all times, the time factor is not relevant.
DMFC products continuously trickle-charge the on-board battery in the materials-handling vehicle. This ensures the battery never reaches a state of deep discharge. Battery charge and power are maintained at high levels, and the battery is not subject to heat damage caused during recharging. Therefore, battery life is increased and battery maintenance needs are reduced.
