ANODE CATHODE ANODE CATHODE 2. Fold across the diagonal creases, tucking the sides into the centre. You should only be able to see some text the correct way up at the top of the triangle you make, in a small yellow traingle. 1. Start with printed side of paper face down on the table. The column of text on the printed side should be horizontal. Fold the paper from one corner to the diagonal corner and unfold again. Repeat with the other diagonal. 3. Fold the two bottom corners up towards the central point of the triangle. The only text visible should be OH- and part of the half cell eqtn. 4. Fold both corners into the centre of the central diamond shape Alkaline OH- OH- ANODE 2H2 + 4OH- → 4H2O + 4e- O2 + 2H2O + 4e-→ 4OH- CATHODE OH- OH- OH- Applications Transport (Cars, Buses) Portable devices (laptops, mobile phones) Power generation (small to large scale) Solid Oxide O2- O2- ANODE 2H2 + 2O2- → 2H2O + 4e- CATHODE O2- O2- O2 + 4e- → 2O2- O2- 8. Fold two points over to meet in the middle then unfold them and fold them the other way and back a few times to make sure it is well creased 6. Tuck the newly made triangles into the pockets on either side. Take care not to accidentally only tuck them under the flap instead of inside it. 9. Blow hard into the hole at one end which should inflate the cube 10. Finished Cube!! 7. Turn over and repeat steps 3-6 on the other side. 5. Fold the top two triangles down towards the points you made in step 4
