最近，有一些出版物报道了尿素的使用，作为氢/燃料电池动力的来源。然而，目前还没有报告专门评估尿素用于这一目的的适用性。本文不仅介绍了尿素(（NH2)(2)CO）作为燃料电池氢载体的特性，而且还介绍了利用存在的巨大天然尿素资源的可行性的研究结果。尿素是一种廉价且可广泛获得的商品，具有发达的制造基础设施和快速增长的产量。这提供了快速实施尿素应用作为氢载体直接或作为氨的来源。与以前考虑的其他工业化学品相比，尿素具有无毒，稳定，因此易于运输和储存的优点。该报告揭示了尿素的自然资源可能是未来长期可持续氢供应的解决方案，并且提取这种自然资源所需的科学知识的现状在很大程度上是了解的。人们认为，如果给予足够的研究关注，这些可持续的路线是可以利用的。
Recently, there have been publications reporting the use of urea, as a source of hydrogen/fuel cell power. There have however been no reports that singularly assess the suitability of urea for this purpose. This article provides not only a perspective on the attributes of urea ((NH2)(2)CO) as a hydrogen carrier for fuel cells but also presents the findings of a review on the feasibility of utilising the enormous natural resource of urea that exists. Urea is a cheap and widely available commodity with well developed manufacturing infrastructure and a rapidly increasing volume of production. This offers rapid implementation of urea for application as a hydrogen carrier either directly or as a source of ammonia. Compared with other industrial chemicals previously considered, urea has the advantages of being non-toxic, stable, and therefore easy to transport and store. This report reveals that the natural resource of urea could be a solution to long-term future sustainable hydrogen supply and that the present status of scientific knowledge necessary to extract this natural resource is in the most part understood. It is considered realistic that these sustainable routes could be exploited if they are given sufficient focus of research attention.
