1. About Bio-Energy 1. About Bio-Energy What is Ethanol? In common usage, Ethanol is often referred to simply as alcohol. It is a straight-chain alcohol and What are biofuels? What are biofuels? its molecular formula is variously represented as EtOH, CH OH,C OH or as its empirical formula C... - Page 4 → 2CH → 2CH OH + 2CO OH + 2CO arable land most suited for food crops to be reserved for food production.

Page 6: How The Fuel Cell Works
Looking forward to consumer electronics and beyond 2. How the fuel cell works: The Direct Ethanol Fuel Cell produces electricity while ethanol reacts at the anode side of the fuel Mirroring the current uses being researched for use in DMFC (Direct Methanol Fuel Cells), the cell. -
Page 7: General Safety Instructions
During the reaction, some of the ethanol is oxidated completely and turns into CO (as in the 3. General Safety Instructions 3. General Safety Instructions reaction #3, while some of the ethanol is oxidated incompletely and turned into acetaldehyde and acetic acid (as in the reactions #1 and #2 ). -

4. Included Parts 5. Experimenting with the Bio-Energy Kit Ethanol storage Tubing Preparing the system Purging valve Supporting base Electric motor Step 1. Remove the fan blade (part H) from the box. Direct Ethanol Fuel Cell Wiring with crocodile clips Step 2. - Page 9 Warning! Experiment 1: Create electricity from ethanol and water Do not allow pure ethanol to enter the fuel cell. The DEFC creates power using 5-15% alcohol only. A concentration higher than 15% could damage the fuel cell and cause it to stop working correctly.
- Page 10 Step 3. Put the lid back to the container. (see 1C) Then connect the two crocodile clips that are attached to the motor to the two separate terminal plates of the fuel cells current collector, which are both located on the upper part of the fuel cell Step 4.
- Page 11 Note: Experiment 2: Exploring polarity Once the fan begins to run slower or stops running, complete the following three steps in order to make the fan run again. Step 1. Connect the positive (red) crocodile clip to the positive side of the fuel cell (red “+” mark), then connect the negative (black) crocodile clip to the negative side of the fuel cell (black “-”...
- Page 12 Experiment 3: Ethanol fuel consumption Step 3. Dip a new pH paper into the solution container. You will notice that the color of the PH paper changes very little. (see 3C-3E) When the fan begins to run slower or stops running completely, this means the ethanol present in the fuel cell chamber is mostly consumed.
- Page 13 2. Using impure ethanol can damage the performance of the fuel cell. You may want to conduct Warning: The safe experimentation range for the Bio-Energy kit is within ethanol concentrations experiments using impure ethanol once all other experiments using pure ethanol are completed.
