At the recently held China Electric Vehicles 100 Forum (2019), Tianji
Automobile displayed solid-state battery and fuel cell exhibition vehicles,
saying that the Tianji ME7 solid-state battery exhibition vehicle is the first
publicly displayed solid-state battery prototype vehicle in China, and its fuel
cell Battery vehicles will serve as mobile charging vehicles and become the core
of China's first fuel cell commercialization plan.
No coincidence. At last year's Guangzhou Auto Show, RG Nathalie, a
subsidiary of AIWAYS, debuted on stage. The power system it uses is also a
methanol reforming hydrogen fuel cell. Data shows that it can accelerate from
100 kilometers to 100 kilometers in 2.5 seconds, with a top speed of 300
kilometers per hour, and a maximum driving range of Reached 1200 kilometers.
At the 3rd International Hydrogen and Fuel Cell Vehicle Conference (FCVC
2018) held in October last year, as the only new car-making force participating
in the exhibition, WM Motor demonstrated a car powered by a methanol fuel cell
system. Passenger cars work on a similar principle to hydrogen fuel cell cars,
except that hydrogen is replaced by methanol.
So many cases seem to indicate a reality, and new car-making forces "favor"
new technologies in the automotive industry. What’s even more interesting is
that the new forces seem to “favor” cutting-edge technologies that have not yet
been mass-produced, or even have not yet entered the industrialization stage of
development.
The solid-state battery deployed by Tianji Automobile has become a hot spot
in global battery technology. In response to the rise of the battery industry in
China and South Korea, Japan has mobilized nationwide efforts to develop
next-generation solid-state batteries, with annual government expenditures
reaching 5 billion to 10 billion yen. The originally relatively weak battery
industries in the United States and Europe are also making every effort to
develop a new generation of solid-state batteries, but they are currently in the
research and development stage. Ouyang Minggao, academician of the Chinese
Academy of Sciences and executive vice chairman of the China Electric Vehicles
Association of 100, predicts that large-scale commercialization of
all-solid-state batteries will only be realized after 2025 to 2030.
The fuel cell vehicle technology solution adopted by Tianji Automobile is
the same as that of AIWAYS. It is a methanol reforming hydrogen production
solution. This is not the current "mainstream" technical route for hydrogen fuel
cell vehicles. The difference is that a methanol reformer is used to replace the
hydrogen storage tank. . In the reformer, the mixture of methanol and water is
converted into hydrogen-rich reformed gas. The reformed gas enters the
high-temperature proton membrane stack to generate electricity and supply
electricity to the outside (i.e., automobiles). A technician who has been
engaged in the development of hydrogen fuel cell vehicles for a long time told
reporters that in the industrial field, the technology of hydrogen production by
methanol reforming is relatively mature and widely used. However, in the field
of transportation, vehicle-mounted methanol reforming hydrogen production
technology is still in the research stage. There are still problems such as
complex systems, long start-up time, low system power, low product maturity, and
carbon emissions that need to be overcome.
As for the methanol fuel cell system displayed by WM Motor, it is even more
"rare". The Direct Methanol Fuel Cell (DMFC) used has the characteristics of
low-temperature quick start, clean and environmentally friendly fuel, and simple
battery structure, but it is smaller than conventional ones. Proton exchange
membrane fuel cells require more platinum catalysts and are currently in the
research stage.
As Fu Yuwu, honorary chairman of the Society of Automotive Engineers of
China, said, the "amazing" performance of the new car-making forces in 2018 was
not only reflected in the realization of mass production, but also in the new
concepts, new ideas and new practices of the new car-making forces. It has had a
big impact on the entire automobile industry. Currently, the global automobile
industry is ushering in a new round of technological revolution, with many new
technology routes springing up like mushrooms after a rain. Compared with the
more "conservative" traditional automobile companies, new car-making forces are
expected to help more cutting-edge technologies from research and development to
production. One of the powerful promoters of application.
However, it is worth mentioning that if you are willing to become a "test
product" of cutting-edge technology, then the new forces must be mentally
prepared accordingly. After all, technical routes that have not been actually
verified by a large number of products will definitely face more risks. and
challenges.
