(PhysOrg.com) -- There are many ways to generate hydrogen, such as water electrolysis and steam reforming of gas, but the hydrogen produced by these methods tends to be combined with other byproduct and residual gases. For this reason, a second step to purify the hydrogen is usually required after it is produced. Now in a new study, scientists have developed a method for generating hydrogen with a purity of more than 99% within a single membrane, eliminating the need for a separate purification step.
