In this month’s Popular Science a new type of fuel cell has been presented that solves the problem of storing hydrogen which can be dangerous if handled improperly. This fuel cell uses alcohol and enzymes to secure hydrogen for the fuel cell. As the alcohol comes into contact with the enzymes at the anode a hydrogen atom is striped of its electron which provides the electricity while the free proton passes through to recombine with oxygen to make water one of the byproducts along with vinegar from the alcohol. This has been tried before but the problem of the enzymes breaking down because of heat has been solved by using more heat tolerant enzymes and coating the fuel cell to prevent the enzymes from having contact with acid or heat.
