What's a zinc air fuel cell? What's the difference between zinc air fuel cell and conventional batteries?
In broad terms, zinc air fuel cell is a kind of battery as well. It provides energy to products that require power to function. But, its working prInciples are different from those of conventional batteries. A fuel cell is actually an electrochemical power reactant. Electric potential is produced when the fuel (zinc), which is introduced into the cell, reacts with oxygen. Conventional batteries, on the other hand, are storage for ready-charged electrons. Electric potential is not produced within conventional batteries. Instead, it is introduced and stored inside the batteries.   
What applications are particularly suited for zinc-air fuel cell?
Electric Vehicles: Bicycles, Motor Scooters, Cars, Buses
Off-Road Recreational Vehicles: Golf Carts
Service Vehicles: Airport Service Carts, Postal Service Vehicles, Wheelchairs
Consumer Electronics: Laptop Computers, Cellular Phones, Camcorders, Digital Cameras
Pleasure Boating, Military Applications
Since zinc-air technology has been around for a hundred years, what distinguishes Powerzinc's zinc-air fuel cell from others in the market?
Although zinc air technology has been around for a long time, it is only restricted to low capacity and low efficient battery applications. In recent years, we have made fundamental breakthroughs in the technology, resulting in a new generation zinc air fuel cell that maintains high capacity, high efficiency, and signifcant longer service life at a lower manufacturing cost. And, our all-in-one model plant in Shanghai will be the first commercialized large-scale plant in the world for zinc air fuel cells.

What is DQFC? What are the available models?
DQFC stands for Dynamic Quick-charge Fuel Cell. It is exclusively developed by Powerzinc through using its patent-pending zinc-air technology. Currently, we have two model available: DQFC-24-3200,DQFC-24-1800, which is for EV application. We will continue to develop new models to meet the Increasing demand of different applications.
What is the service life of a DQFC?
The service life of a DQFC depends on its gas diffusion electrode (GDE). Our GDE is able to last for at least 400 cycles of anode regeneration. But, this should not be a concern for end-users because they will get a newly fueled DQFC in replace of their discharged DQFC each time they go to a DQFC Refuel Outlet for refuel.
Is it true that the DQFC series can only be used on light EVs (LEVs)?
Our DQFC series can be used on larger EVs as well. The prInciple behind this is just like connecting a series of conventional batteries in a circuit to achieve higher power. It is true that the current models of the DQFC series have limited power (enough to power a LEV but insufficient to power a larger EV), but when you connect a few of them together, their combined power would be more than enough to power large EVs. 
Is DQFC series available now?

Currently, we do not sell our zinc-air fuel cells directly to end-users. We only sell samples (DQFC-24-1800, 24V, 76 AH) to EV manufacturers technical evaluation purposes. Manufacturers are required to sign the Non-Disclosure Agreement (NDA) and Disclaimer of Warranties & Liability forms, and to provide detailed information on their business, products and applications prior to the delivery of the samples.

All samples are provided to customers "as is" and without warranty of any kind, and all express or implied warranties are excluded.

Where to replace the zinc plates?

The zinc plates have to be replaced after the exhaustion. For samples and small quantity of zinc air fuel cells, customers can replace the plates manually. But for regular orders, the zInc plate replacement process has to be done automatically in a Regeneration Plant. The scale of the Regeneration Plant is dependent upon the volume of usage of the fuel cells. We license our technology to manufacturers/distributors to set up Regeneration Plants in different regions. If the demands are high in certain regions, we are interested in building the Regeneration Plants with our own resources.

Instead of using the conventional Electric recharging method, Powerzinc's DQFC series uses mechanical refueling. Why?
Conventional rechargeable EV batteries are charged through plugging into Electric sockets. The charge normally takes a few hours. Even then, the batteries are often not fully charged. As a result, EVs can only run for a limited distance before another charge is required. Long hours of recharging also shorten the service life of the batteries. Powerzinc's DQFC series, on the other hand, does not have this kind of problems. Mechanical refueling would only take a few minutes at a DQFC Refuel Stations. Basically, the discharged DQFC is removed and replaced with a fully refueled DQFC. Powerzinc plans to set up a network of refuel outlets at existing gas stations. In this way, EV drivers can drive their vehicles for a significant longer distance without worrying about finding a place to refuel. DQFC-powered EVs will fuction very similiar to gasoline-powered cars in terms of driving range, yet more environmental friendly. Moreover, by replacing the DQFC frequently at refuel outlets, we eliminate the problem of short battery service life. This will ensure the DQFC end users have will always at its top performance.  
What is the cost of refueling a DQFC?
It varies with regions. It depends largely on the cost of material, labor, Electricity etc. of each region.
How long would it take to refuel a DQFC?
The process usually takes less than 5 minutes.
Can the DQFC series applicable in areas other than EVs? If yes, what are the advantages DQFC has over other batteries in these applications?
The current models of DQFC are specifically designed for EVs. In the near future, we will also manufacture (1) refuelable and (2) disposable DQFCs that can be used on consumer electronics and Electrical appliances. The most distinct advantage DQFC has over other types of batteries is its high specific energy, which allows longer runtime.
If the DQFC series is widely adopted, will its refueling (zinc oxide regeneration for discharged anodes) put on extra stress on the existing power grid, resulting in another form of energy crisis?
No. On contrary, we believe that the adoption of the DQFC series can in fact increase the efficiency of existing power plants. Power plants can make use of their excess energy during off-peak hours to regenerate the zinc oxide . In regions where energy is excess or economical, local power plants can actually store their excess energy in the regenerated zinc, and distribute to regions where energy is scarce and expensive.
Is Powerzinc just targeting the Asian markets?
No. We plan to market our products globally. But, at present, due to the immediate demand from Taiwan and mainland China, and the limited capacity we have on our current manufacturing facility, we can only focus on these two key markets. But, eventually, we will expand into markets throughout the world. We welcome any companies to become our strategic alliances.
Is Powerzinc a publicly traded company?
No. it is still privately owned at present time.Powerzinc welcome interested qualified investors to join its fast growing business.The company has plan to go public in the future. Please refer to our web site regularly for further development.
