Abstract
This paper describes the properties of the ammonia reformer in the fuel cell vehicle proposed in the first report. The effects of the pressure, the temperature, and the space velocity in the reformer on the hydrogen conversion rate and the residual ammonia concentration have been investigated. To reduce the residual ammonia the authors have designed and made an ammonia separator that is necessary even in the optimal condition obtained in the experiment. The separator can be consequently demonstrated to be practical, because it has achieved that the ammonia concentration in the outlet of the separator was below a measurement limit at a temperature of about 25℃.
