Chapter Twelve

Future of Fuel Cells and Hydrogen

12.1 Introduction

PEM fuel cells need hydrogen as fuel. Hydrogen is not a source of energy, and hydrogen is not a readily available fuel. However, in the future hydrogen could be something like electricity—an intermediary form of energy or an energy carrier. Just like electricity, hydrogen can be generated from a variety of energy sources, be delivered to end users, and at the user end it can be converted to useful energy efficiently and cleanly. Electricity infrastructure is already in place, but hydrogen infrastructure would need to be built.

It is this lack of hydrogen infrastructure that is considered one of the biggest obstacles to fuel cell commercialization. Commercialization of high-temperature ...
