I failed a course, and the system became my study supervisor.

Chapter 64 Topic Determination
In the next few days, the classes continued and Brother Hong was still in the classroom, but he was no longer so outgoing and was polite to everyone.

Xu Ling didn't have the time to care about him and just waited for the result of Chen Qingguo's punishment.

Because the course was short and the content was quite heavy, Shen Huanan lectured very quickly. In addition, the knowledge of power supplies was indeed somewhat unfamiliar to these freshmen, and many students complained bitterly.

Only Xu Ling and Yu Wenkai were slightly better, but they could only barely digest the course content.

"Who can draw the circuit diagram on the blackboard for the circuit I talked about yesterday?"

Shen Huanan looked around and asked.

Xu Ling doesn't like to show off and didn't react at all.

Instead, Yu Wenkai walked up to the podium, picked up a piece of chalk, and quickly drew several different circuit diagrams.

It includes rectifier circuits such as half-wave rectifier and bridge rectifier.

Shen Huanan praised him repeatedly, but Xu Ling was the only one who was whispering in his heart.

Teacher, you've been deceived! He's a junior!
Obviously, the last few classes have focused on the application of power supplies in circuits, protection, and so on. The internal principles of different types of batteries are the final part of the course.

Finally, on the fourth day of the course, Chen Qingguo finally announced how to deal with the Hong Kong guy.

Chen Qingguo's original words were: "This student's inappropriate remarks should, of course, be dealt with seriously. However, considering that his remarks were not widely disseminated, the impact was not too severe, and he admitted his mistake promptly and expressed his willingness to repent.

After discussion among our faculty, we unanimously decided to give him a serious warning and cancel all opportunities for awards and honors during his undergraduate studies."

"He got such a good deal. I still remember his face."

Yu Wenkai seemed a little dissatisfied and his tone was still indignant.

But objectively speaking, Xu Ling believes that such punishment is already fair, and Hong Kong Brother's remarks did not cause much consequences.

Although Brother Hong was happy about the result, he was still upset about the punishment of having his evaluation cancelled.

He doesn't care about how much scholarship he gets, he cares about the honor.

But now, there is no chance.

For a moment, he really felt a little regretful.

The course continued, and Shen Huanan finally talked about the issue that Xu Ling was most concerned about.

"Classmates, the course is coming to an end. I would like to discuss two topics: the principles of PEMFC and the use of the PEMFC simulator, which we generally call PEME."

Xu Ling gave a simple summary of the principle of PEMFC, which is the reverse reaction of water electrolysis.

At the anode, hydrogen enters the anode chamber after being humidified, passes through the electrode diffusion layer, and reaches the interface between the catalyst layer and the proton exchange membrane. Under the action of the catalyst, it decomposes into protons and electrons. The protons are transferred to the cathode through the proton exchange membrane, and the electrons flow through the external circuit, forming an electric current.

At the cathode, oxygen reaches the interface and reacts with hydrogen ions (protons) under the action of the cathode catalyst to produce water.

PEME, as the name suggests, is a simulation environment powered by mathematical modeling. By using simulation, various PEMFC parameters can be modified to optimize the system without risking damage to the original components, making the process safer and more economical.

"Holy crap! This thing is awesome!" Xu Ling exclaimed in amazement, then turned to Yu Wenkai and asked, "You're more experienced. Does our school have this thing?"

After a brief thought, Yu Wenkai replied, "Yes, but the one Mr. Shen introduced is the latest one. I'm not sure about that."

What excited Xu Ling was that Shen Huanan said that students from Shanghai University could use it for free during the entire exchange period.

This trip to Hong Kong was really worth it!

So the course is over, and next is a two-week project research period.

To be honest, it is a fantasy to expect a group of freshmen who have just learned the basics to achieve something great in two weeks.

Chen Qingguo certainly knew this, so when choosing topics, he suggested that students choose some simple details and did not set very high requirements.

CityU was well prepared for this research project, with 20 students and 10 assistant teachers. Obviously, the students worked in pairs, and they were free to form teams.

Xu Ling naturally formed a team with Yu Wenkai.

Coincidentally, their assistant teacher is Shen Huanan.

Xu Ling expressed his curiosity about this.

How much bonus can Shen Huanan get? He does the work of two people alone.

But at the same time, Xu Ling also realized that this research project was an opportunity for him!
Not only can you use PEME to complete the unfinished simulation of your ABS, but you may also be able to find some optimization methods to take your ABS to a higher level.

"Do you have any ideas for the topic?"

Xu Ling asked tentatively.

"No."

Yu Wenkai shook his head.

I'm glad you don't have it.

Xu Ling was instantly excited and said quickly, "Then you might as well take a look at this article of mine."

After saying that, Xu Ling immediately passed the file to Yu Wenkai.

"ABS system?"

Yu Wenkai's interest was piqued. He had never heard of a battery system called ABS.

It took Yu Wenkai about ten minutes to finish reading the entire content.

"So, you want to use this research topic to write your own thesis?"

Yu Wenkai said with a smile.

After he said that, Xu Ling immediately felt a little embarrassed. He nodded and said nothing.

"You're quite smart and know how to utilize resources. Then I'll do this with you. I don't have any good ideas anyway."

Xu Ling had expected Yu Wenkai to mock him, but when he heard that he agreed directly, he was filled with gratitude and said excitedly, "Thank you, thank you. I'll send the article to Professor Shen and report our topic."

"Haha, what's there to thank me for? Just keep working on it. If the results are good, consider me first if you want to sell it in the future."

Yu Wenkai said with a smile.

Xu Ling nodded, not caring about the issue of selling.

Xu Ling just took it as a joke.

It was a long time before Xu Ling realized that Yu Wenkai was not joking.

Of course that's all for later.

The most urgent thing is to report the topic as soon as possible.

Shen Huanan did not realize that the paper sent by Xu Ling was written by Xu Ling himself. He thought it was just an excerpt of the paper that Xu Ling found somewhere.

But Shen Huanan was still surprised by the content of the paper, and immediately thought about its feasibility. Finally, he was surprised to find that it seemed to be possible.

Who published this paper? Why haven't I seen it before?
Shen Huanan was registering Xu Ling's topic, feeling confused.

The title of Xu Ling's topic was finally finalized: "Simulation Verification and Optimization of ABS System"
