Gentlepersons:

       We  are  counsel  to  DCH  Technology,  Inc. a Delaware corporation, (the
"Company").  We  have  assisted the Company in its preparation of a Registration
Statement on Form S-8 (the "Registration Statement") under the Securities Act of
1933,  as amended (the "Securities Act"), registering 5,000,000 shares of common
stock,  $.01  par  value,  of  the  Company  (the  "Common Stock") issuable upon
exercise  of  options granted and to be granted under the Company's Amended 2001
Stock  Option  Plan  (the  "Plan").

     In  rendering  this  opinion,  we have considered such questions of law and
examined  such  statutes  and  regulations,  corporate records, certificates and
other  documents  and  have  made  such  other  examinations,  searches  and
investigations  as  we  have  considered necessary. In such examinations we have
assumed  the genuineness of all signatures and the authenticity of all documents
submitted  to  us  as  originals and the conformity to original documents of all
documents  submitted to us as certified or as photocopies or telecopies. We have
not  made  an independent examination of the laws of any jurisdiction other than
California  and  the federal laws of the United States, and we do not express or
imply  any  opinions  in  respect  to  the  laws  of any other jurisdiction. The
opinions  expressed herein are based on legislation and regulations in effect on
the  date  hereof.

     Based  on  and  subject  to  the  foregoing, we are of the opinion that the
Common Stock, when issued pursuant to the exercise of options under the Plan and
the  purchase  price  therefor  has  been paid, will be duly and validly issued,
fully  paid  and  nonassessable  shares  of  Common  Stock.

     We  assume  no  obligation  to  advise  you of any changes to the foregoing
subsequent to the delivery of this opinion letter.  This opinion letter has been
prepared  solely  for your use in connection with the filing of the Registration
Statement on the date of this opinion letter and shall not be quoted in whole or
in  part or otherwise referred to, nor filed with or furnished to or relied upon

by  any  governmental  agency or other person or other entity, without the prior
written  consent  of this firm.  Our opinion is expressly limited to the matters
set  forth  above and we render no opinion, whether by implication or otherwise,
as  to  any  other  matters  relating  to  DCH  Technology,  Inc. or the Shares.

     We  hereby  consent  to  the  filing  of  this opinion as an Exhibit to the
Registration Statement. This consent is not to be construed as an admission that
we  are  a  person  whose  consent is required to be filed with the Registration
Statement  under  the  provisions  of  the  Securities  Act.
