When auto industry remains focused on hydrogen fuel
cell, a new zinc-air fuel cell technology developed
by a US-based company has recently been introduced to
Shanghai. The zinc-air fuel cell powered electric bicycles
are now available for ordinary consumers in Shanghai.
The biggest advantage of this zinc-air fuel cell powered
bicycle is its extended riding range. For the first
time, an electric bicycle can run between 50-200 km
range. Another unique feature that is different from
conventional electric recharge process is that this
fuel cell is mechanically refueled and the refuel process
only takes about 3 minutes.
Industry insiders are all aware that zinc-air fuel
cell technology was first developed more than a hundred
years ago. Its specific energy is 5-7 times that of
Lead-acid. After spending significant amount of time
and resources developing the technology, Powerzinc has
made many technology breakthroughs. They overcame the
technical barriers in low power, instability, and unreliability.
Today Powerzinc is the only company in the world that
has commercialized products available to the market.
The Company has filed patent applications in the U.S.
and more than 126 countries. The Company was co-founded
by Chinese Americans.
Zinc-air fuel cell is safe, non-polluting, low cost
and refuelable, and produces high energy and high power.
Industry experts believe it is an ideal power source
for electric cars and electric motor scooters. If the
technology is utilized on electric buses, it would greatly
reduce air and noise pollution. According to Professor
Wang, SiMing, the nation¡¯s renowned scientist in theoretical
physics, zinc-air fuel cell is scientifically proven
and has tremendous potential in a variety of applications.
Powerzinc¡¯s success in zinc-air fuel cell development
is also recognized and supported by the US government.
On September 2001, Mr. Marvin Singer of Fossil Energy
Office of US Department of Energy (DOE) and Mr. Patrick
Davis of Energy Efficiency and Renewable Office visited
Powerzinc Shanghai plant. Mr. Singer made many positive
comments in his report to Assistant Secretary of DOE
after the visit. The US-China Energy and Environmental
Technology Center, which was formed by US Department
of Energy and Ministry of Science and Technology of
China (MOST), has strongly recommended Powerzinc¡¯s zinc-air
fuel cell to Ministry of Science and Technology of China
(MOST) as a key development project.
According to the Company, it has already established
R&D center and manufacturing plant. The first generation,
commercialized zinc-air fuel cell has passed the evaluation
tests of Shanghai Environmental Product Inspection Station.
They have just started trial distribution. The company
has recently introduced the world¡¯s first zinc-air fuel
cell powered passenger car in China.
China has the world¡¯s largest zinc reserve. While the
commercialization of hydrogen fuel cell facing the issues
with high cost, large investment on infrastructure,
and bottleneck of technology, the emerging zinc-air
fuel cell technology could pave the way for a faster
commercialization of environment-friendly vehicles.
And it could become a reality in China.
