Twenty 海角社区 Engineering students working on project INNOVA- a hydrogen fuel cell-powered urban concept vehicle- placed second in its category at the Shell Eco-Marathon Americas 2023 regional competition at the Indianapolis Motor Speedway April 12-16. 

The students, led by Engineering Professor William Brownlowe and Technical Advisor Griff Francis, competed against teams from North and South America in the annual 鈥済lobal academic program that challenges talented students to design and build cars, considering technical and behavioral factors to achieve game-changing energy efficiency results,鈥� according to its . 

The project INNOVA team includes 海角社区 students Franzine Bagalawis, Philip Charron, Katherine Cocar, Joe DeFazio, Eric Fisher, Ben German, Nophir Harrell, Paul Jacobs, Gabriella Joella, Rob Kay, Nathan Mayer, Gerald Moss, Tom Quinn, Andrew Rubenstein, Claudia Savella, John Schuhl, Shawn Sherwood, Dominic-Evon Torres, Sabrina Turner and Melody Welsh.

鈥淛ust being there, being at the Brickyard at Indy, the granddaddy of racetracks in the U.S. and working in the same garages as the Indy car teams do,鈥� said Brownlowe of the experience, 鈥渋t was huge.鈥�

Following a rigorous inspection, the Innova Car was tasked with completing four laps around the 2.4-mile looped inner track of the motor speedway in less than 35 minutes. The goal was to determine which car had the best fuel economy, but cars also needed to maintain a minimum speed. The Innova car was able to complete the course with 30 seconds to spare, explained Francis. 

The final competition was for the best car in each category. Nine cars competed and, based on a car鈥檚 previous runs, each team was allowed a certain amount of fuel. Unfortunately, the Innova car wasn鈥檛 able to complete the course with the allotted fuel it was given.

鈥淗owever, the only other fuel cell team that qualified for the event, did not get off the start line,鈥� said Francis.

From a technical standpoint, the Innova car passed its rigorous inspection, but the competition exposed a big weakness.

鈥淭echnologically, our car is good,鈥� said Brownlowe. 鈥淎erodynamically, it鈥檚 not.鈥�
Racing the car on the inner track showed the car could not stand up to strong wind resistance, he said.

鈥淵ou鈥檙e getting buffeted around and you know if you鈥檙e getting buffeted, you鈥檙e losing energy,鈥� Brownlowe explained. 鈥淥ur aerodynamic signature was horrible, and it was killing our mileage. When you have this little power to move you along, you鈥檝e got to use quite a bit of fuel to keep things going.鈥�

Still, Brownlowe was incredibly proud of his students for their achievement.

鈥淲hat we were able to accomplish since January, especially with new students who got involved, without each and every one of them, we wouldn鈥檛 have made it,鈥� he said. 鈥淓veryone was mission critical to this. And they all stepped up to the plate and did what needed to be done. I鈥檓 very proud of what all of us were able to accomplish.鈥�

Overcoming obstacles

The Innova team faced several challenges during its time in Indianapolis, including a few that at first appeared insurmountable. One major hurdle was the fact that the team traveled to the competition with a leaking hydrogen fuel cell, which would have cost nearly $8,000 to replace. 

鈥淚 had said it before we left,鈥� said Brownlowe, 鈥渨e鈥檙e not going to make it through the technical inspection with the fuel cell like this.鈥� 
The competition鈥檚 technical inspectors suggested a radical workaround to try to help the team solve the problem, but ultimately, it was sportsmanship that saved the Mustangs.

Another team that didn鈥檛 pass its technical inspection, had an extra fuel cell the Innova team needed to compete and was willing to part with it to help a competitor in need. 
鈥淭hey were initially skeptical. A fuel cell is not something you would readily lend to someone because the knowledge of how to operate and maintain it is critical,鈥� said Brownlowe. 鈥淵ou could do what we did to ours, which is damage it. We over-pressurized it. That鈥檚 what caused it to leak. So, you鈥檙e pushing a lot of hydrogen out of the cell and you鈥檙e not even using it. It鈥檚 like blowing gasoline out your tail pipe, and you鈥檙e not even burning it.鈥�

As a show of thank you, the Mustangs nominated the team for the Shell Eco-Marathon Spirit of the Event Award, which it eventually won, and its members took home a $3,000 prize. 

Another issue the Mustangs overcame was the size of its energy storage system, or super capacitor bank.

鈥淪o, we encountered, not so much, failures in our design, as shortcomings that were discovered when we got there,鈥� said Brownlowe. 鈥淲e didn鈥檛 have a supercapacitor bank of any great significance. We noticed that all of the other cars that were in our hydrogen urban concept category had substantial supercapacitor banks. And we didn鈥檛.鈥�
To keep his team competitive, Brownlowe overnight ordered a larger super capacitor bank.
鈥淭he team was ecstatic,鈥� he said. 鈥淭hey were so, so happy.鈥�

Planning for next year

Because the team was able to pass inspection and compete on the track, students were introduced to a higher level of competition, said Brownlowe.

鈥淣ow we know what we鈥檙e up against for next year,鈥� he said. 鈥淲e鈥檙e already looking at redesigning the vehicle chassis and body because that鈥檚 our aerodynamic issue. Each year that we go we kind of see things that get us up into the competitive range of these teams. We want to win first place in our category. If we can do that, we can consistently get into the regional championship round. And if we can place in the top four, we go to World Driving Championship.鈥�

To build a new car from scratch for next year鈥檚 competition, the team will need to fundraise to afford some of the parts. Brownlowe is hoping to raise $25,000 in order to meet the needs of the car. In 2020, Dorman Products, of Colmar, donated $5,000 that ended up helping design this year鈥檚 car. The team will need similar donations again for next year in order to stay competitive. 鈥淲e have to replace our fuel cell,鈥� he said. 鈥淲e need two new, we need to do two new bodies, we鈥檙e going to need new wheels, we need new tires. It鈥檚 a lot of work.鈥�
