T1W8 Group Discussion: Compare the designs of the Benetto Cell to the Beaker Cell. How is the design of the Benetto Cell more optimised than the Beaker Cell to obtain higher voltage? by https://padlet.com/teo_siew_lian/designofbenettocell en-us 2018-07-12 02:16:51 UTC 2019-02-28 06:42:32 UTC hello@padlet.com https://padlet-assets.s3.amazonaws.com/icons/Lightdecrease.png Observations and explanation 1) Airtight Explanation teo_siew_lian https://padlet.com/teo_siew_lian/designofbenettocell/wish/270005823

1) Airtight: 
- Lack of oxygen increases the efficiency of the MFC. 

2) Size of MFC:
- 
3) Surface area to volume ratio:
- The larger the surface area, the more electrons captured. Furthermore, the rate of diffusion of electrons increases.

2)The benetto cell is airtight, thus less air enters the cell compared to the open beaker cell. Increasing the efficiency of the transport of electrons compared to the beaker cell.

2) Air tight, water with different amounts of oxygen has different pH levels which will affect the efficiency of the yeast.
3) Since it's air tight, there is no convection taking place. The temperature will not be affected so the yeast efficiency will not be affected.

- air tight chambers so lesser external factors can affect the chemical and the amount of energy it produces
- the air tight chamber keeps the temperature at the optimum efficiency to produce energy
- the beneto cell links the cells in series thus it produces more energy but for a lesser period of time, when using the beaker cell the voltage remained more constant
- more reliable because lesser external factors can affect it

The larger surface area to volume ratio of the carbon fiber allows more electrons to move through faster.
2. The airtight chambers prevent oxygen from entering, thus, the process is more efficient.
3. The results noted are much reliable because lesser external factors are able to affect the results, for instance, oxygen, temperature etc.

Increase in cathode chamber containing potassium ferricyanide (which gets used up in the reaction) should increase the lifespan of the cell. 4. chealcheal https://padlet.com/teo_siew_lian/designofbenettocell/wish/330862814
