Get it right – Electrochemical Cells

This aim if this blog post is to equip you with an aid memoir – something you can copy, paste, edit and print out to aid your revision. The reasoning behind this post is from my experience as an examiner. In my opinion (and this may not be one shared by the IB) students tend to answer questions on electrochemical cells quite poorly. This is possibly due to the topic being one of the last topics to be taught – maybe ...

Fuel Cells

Fuel cells a type of electrochemical cell. They work on the idea that one day they could replace the inefficient conversion of fuels to heat (approx 40%)  and then electricity with a more efficient (approx 80 - 85%) and cleaner way of producing electricity. Water is produced as a 'waste' product.   They are different electrochemical cells to the ones you will have studied at IB as they are open systems - fuel (in the form of Hydrogen and Oxygen) must be ...
