Hydrogen Cell
A hydrogen fuel cell generates power from water and heat. They rely on an electrochemical reaction to produce the power. It has two electrodes, an anode and a cathode which is separated by a membrane. Oxygen passes over one electrode and hydrogen over the other. The hydrogen ions move through the electrolyte to the cathode where they combine with oxygen and electrons to produce water. They are kind of like a battery.

Solar Panel
When light hits a solar panel it turns the energy into and electrical current. When sun hits most object it just turns into heat. Individual electrons in bonds get a greater energy level and can move around more freely than when it was bound. That electron can then move around freely, which produces an electrical current to power things.

Series and Parallel Circuits
A series circuit only has one path for the current to flow. So when one thing breaks like a bulb blowing nothing in the whole circuit works. This is why in some Christmas lights when one bulb goes out, the rest pf the bulbs in the circuit go out because there is no other path for the current to flow. In a parallel circuit there is more then one path for the current to flow so if one bulb blows the current goes around it and the rest of the circuit still works.

Reflection
I learned that solar panels are not that efficient, and hydrogen cells are complicated to use. I also learned a lot about circuits and how to use a breadboard. The car sometimes barley had enough power from the hydrogen cell to work and sometimes it would work fine. We also had issues with the car turning to one side so it couldn't even get to the finish line.
