WATERLOO —
Researchers at the University of Waterloo have designed a new hydrogen fuel cell for the car, which they say can make it cheap enough to compete with internal combustion engines.
The new fuel cells have a life span of 10 times longer than the current fuel cell technology, and this improvement can make them more competitive in quality
Production and may help usher in a new wave of emissionsfree vehicles.
Li Xianguo, director of Waterloo's fuel cell and Green Energy Laboratory, said the current fuel cell technology is affected by changes in the power load when the car stops from drivingand-
High traffic-
Between the highway and other driving conditions.
"If you have this variability, the life cycle will be greatly shortened," he said . ".
The hydrogen fuel cell currently has a life span of about 3,000 hours, but the UW research team has increased it to nearly 30,000 hours, Li said.
Hydrogen is stored in a storage tank inside the vehicle, and when combined with oxygen outside the vehicle, a chemical reaction occurs, generating electricity.
Vehicles can supply fuel like traditional gas vehicles.
It takes about five minutes to fill a hydrogen tank-
The driving range is almost the same.
The only discharge is water.
To improve life, Lee and his team split the traditional fuel cell units into three smaller units.
The physical size and energy output remain the same, but the three units provide more control over the variable electrical load requirements.
Slow City driving can be done by on-
Board battery, allowing the fuel cell to be turned off completely.
When the battery runs at low speed or requires a higher speed, one of the fuel cells can be activated to run the car and charge the battery.
The car can also cycle between three units and take a break while other units are running.
"In this way, they either open or close --
Zero or 100
So the battery works under its best design conditions and has a longer life, "said Li.
The results of the research team published in the journal Applied Energy indicate that on-
Board fuel cells can be increased by 11 over current batteries. 8, 4. 8 and 6.
Cities, highways and cities, respectively-
Road cycle.
The redesign also gives the driver the option if one of the units fails on the road.
"If there is a problem with a unit, you still have two units working (cells)
He said: "He allowed the driver to bring the car home safely or to the repair shop.
"In the old design, the whole system will not work if there is a problem.
"Li cooperated with Zhang Hongtao, chief researcher, Liu Xinzhi, professor of mathematics at Waterloo, and Jin Yueyan, Swedish energy expert and professor.
Toyota's Mirai sedan is one of the first mass-produced hydrogen fuel cell electric vehicles on the market, but starts at about $60,000.
Since the launch of the car in 2014, only about 5,000 units have been sold.
The key to making technology economically practical for a wider range of consumers is to achieve a broad range
Large-scale production.
Li estimates that if millions of cars are built each year using the technology, that goal can be achieved.
He pointed out that this may sound like a lot, but in a country like China where hydrogen fuel cells are more widely accepted, it could happen that 28 million cars were sold on the market in 2018.
"Fuel cells are very popular, or at least the concept is there," Li said . ".
